Problem
"Given an array representing a branch of a tree that has non-negative integer nodes
your task is to pluck one of the nodes and return it.
The plucked node should be the node with the smallest even value.
If multiple nodes with the same smallest even value are found return the node that has smallest index.
The plucked node should be returned in an array, [ smalest_value, its index ],
If there are no even values or the given array is empty, return [].
Example 1:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 2:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 3:
Example 4:
Explanation: 0 is the smallest value, but there are two zeros,
so we will choose the first zero, which has the smallest index.

"Given an array representing a branch of a tree that has non-negative integer nodes
your task is to pluck one of the nodes and return it.
The plucked node should be the node with the smallest even value.
If multiple nodes with the same smallest even value are found return the node that has smallest index.
The plucked node should be returned in an array, [ smalest_value, its index ],
If there are no even values or the given array is empty, return [].
Example 1:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 2:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 3:
Example 4:
Explanation: 0 is the smallest value, but there are two zeros,
so we will choose the first zero, which has the smallest index.

"Given an array representing a branch of a tree that has non-negative integer nodes
your task is to pluck one of the nodes and return it.
The plucked node should be the node with the smallest even value.
If multiple nodes with the same smallest even value are found return the node that has smallest index.
The plucked node should be returned in an array, [ smalest_value, its index ],
If there are no even values or the given array is empty, return [].
Example 1:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 2:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 3:
Example 4:
Explanation: 0 is the smallest value, but there are two zeros,
so we will choose the first zero, which has the smallest index.

"Given an array representing a branch of a tree that has non-negative integer nodes
your task is to pluck one of the nodes and return it.
The plucked node should be the node with the smallest even value.
If multiple nodes with the same smallest even value are found return the node that has smallest index.
The plucked node should be returned in an array, [ smalest_value, its index ],
If there are no even values or the given array is empty, return [].
Example 1:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 2:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 3:
Example 4:
Explanation: 0 is the smallest value, but there are two zeros,
so we will choose the first zero, which has the smallest index.

"Given an array representing a branch of a tree that has non-negative integer nodes
your task is to pluck one of the nodes and return it.
The plucked node should be the node with the smallest even value.

If multiple nodes with the same smallest even value are found return the node that has smallest index.
The plucked node should be returned in an array, [ smalest_value, its index ],
If there are no even values or the given array is empty, return [].
Example 1:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 2:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 3:
Example 4:
Explanation: 0 is the smallest value, but there are two zeros,
so we will choose the first zero, which has the smallest index.

"Given an array representing a branch of a tree that has non-negative integer nodes
your task is to pluck one of the nodes and return it.
The plucked node should be the node with the smallest even value.
If multiple nodes with the same smallest even value are found return the node that has smallest index.
The plucked node should be returned in an array, [ smalest_value, its index ],
If there are no even values or the given array is empty, return [].
Example 1:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 2:
Explanation: 2 has the smallest even value, and 2 has the smallest index.

"Given an array representing a branch of a tree that has non-negative integer nodes
your task is to pluck one of the nodes and return it.
The plucked node should be the node with the smallest even value.
If multiple nodes with the same smallest even value are found return the node that has smallest index.
The plucked node should be returned in an array, [ smalest_value, its index ],

your task is to pluck one of the nodes and return it.
The plucked node should be the node with the smallest even value.
If multiple nodes with the same smallest even value are found return the node that has smallest index.
The plucked node should be returned in an array, [ smalest_value, its index ],
If there are no even values or the given array is empty, return [].
Example 1:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 2:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 3:
Example 4:
Explanation: 0 is the smallest value, but there are two zeros,
so we will choose the first zero, which has the smallest index.
Constraints:
* 1 <= nodes.length <= 10000
* 0 <= node.value
pluck(arr: [4, 2, 3]) == [2, 1]

"Given an array representing a branch of a tree that has non-negative integer nodes
your task is to pluck one of the nodes and return it.
The plucked node should be the node with the smallest even value.
If multiple nodes with the same smallest even value are found return the node that has smallest index.
The plucked node should be returned in an array, [ smalest_value, its index ],

"Given an array representing a branch of a tree that has non-negative integer nodes
your task is to pluck one of the nodes and return it.
The plucked node should be the node with the smallest even value.
If multiple nodes with the same smallest even value are found return the node that has smallest index.
The plucked node should be returned in an array, [ smalest_value, its index ],
If there are no even values or the given array is empty, return [].
Example 1:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 2:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 3:
Example 4:
Explanation: 0 is the smallest value, but there are two zeros,
so we will choose the first zero, which has the smallest index.

The plucked node should be returned in an array, [ smalest_value, its index ],
If there are no even values or the given array is empty, return [].
Example 1:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 2:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 3:
Example 4:
Explanation: 0 is the smallest value, but there are two zeros,
so we will choose the first zero, which has the smallest index.
Constraints:
* 1 <= nodes.length <= 10000
* 0 <= node.value
pluck(arr: [4, 2, 3]) == [2, 1]
pluck(arr: [1, 2, 3]) == [2, 1]
pluck(arr: [] as [Int]) == [] as [Int]
pluck(arr: [5, 0, 3, 0, 4, 2]) == [0, 1]

"Given an array representing a branch of a tree that has non-negative integer nodes
your task is to pluck one of the nodes and return it.
The plucked node should be the node with the smallest even value.
If multiple nodes with the same smallest even value are found return the node that has smallest index.
The plucked node should be returned in an array, [ smalest_value, its index ],
If there are no even values or the given array is empty, return [].
Example 1:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 2:

### Explanation:
This solution first creates an empty array to store even values. It then iterates through the given array and checks if each value is even. If it is, it adds the value to the `evenValues` array and updates the `smallestValue` and `smallestIndex` variables if the value is smaller than the current smallest value. If there are multiple values with the same smallest value, it chooses the first occurrence of the smallest value and updates the `smallestIndex` variable. If the smallest value is 0, it also updates the `smallestIndex` variable. Finally, it returns an array containing the smallest value and its index.

The function first initializes two empty arrays, `evenValues` and `smallestValue`, to store the even values and the smallest even value, respectively. It also initializes a variable `smallestValue` to `Int.max` to store the smallest even value.
The function then iterates through the array using the `enumerated()` method to get the index and value of each element. If the value is even, it appends it to the `evenValues` array and updates the `smallestValue` and `smallestIndex` variables if it is the smallest even value. If the value is 0, it appends it to the `evenValues` array and updates the `smallestValue` and `smallestIndex` variables if it is the smallest even value.
If there are no even values in the array, the function returns an empty array. If there is only one even value in the array, the function returns an array with the smallest even value and its index. If there are multiple even values in the array, the function returns an array with the smallest even value and its index.
### Time Complexity:
The time complexity of this function is O(n), where n is the length of the input array.
### Space Complexity:
The space complexity of this function is O(1), since the function only uses constant amount of memory.
### Test Cases:
```swift
print(pluck(arr: [4, 2, 3])) // [2, 1]
print(pluck(arr: [1, 2, 3])) // [2, 1]
print(pluck(arr: [] as [Int])) // [] as [Int]
print(pluck(arr: [5, 0, 3, 0, 4, 2])) // [0, 1]
```
### Conclusion:
This problem can be solved using a simple for loop and a few if statements. The time complexity of this solution is O(n), and the space complexity is O(1). The solution is simple and easy to understand, but it may not be the most efficient solution for large arrays.func pluck(arr: [Int]) -> [Int] {
var smallestValue = Int.max
var smallestIndex = -1
var evenCount = 0
var zeroCount = 0
for (index, value) in arr.enumerated() {
if value == 0 {
zeroCount += 1
} else if value % 2 == 0 {
evenCount += 1
if value < smallestValue {
smallestValue = value
smallestIndex = index
}
}
}
if evenCount == 0 || arr.isEmpty {
return []
}
if zeroCount > 0 {
return [0, smallestIndex]
}
return [smallestValue, smallestIndex]

### Conclusion:
In this problem, we have to pluck one of the nodes from a branch of a tree that has non-negative integer nodes. We have to return the node with the smallest even value and its index. If multiple nodes with the same smallest even value are found, we have to return the node that has smallest index. We have to use a loop to iterate through the array and check if the current node is even and if it is smaller than the smallest even value. If it is, we update the smallest even value and its index. If multiple nodes with the same smallest even value are found, we have to return the node that has smallest index. We have to use a variable to keep track of the smallest even value and its index, and we have to use an if statement to check if the array is empty or not. Finally, we have to return the result array.func pluck(arr: [Int]) -> [Int] {
var smallestEven = Int.max
var smallestIndex = 0
for i in 0..<arr.count {
if arr[i] % 2 == 0 && arr[i] < smallestEven {
smallestEven = arr[i]
smallestIndex = i

"Given an array representing a branch of a tree that has non-negative integer nodes
your task is to pluck one of the nodes and return it.
The plucked node should be the node with the smallest even value.
If multiple nodes with the same smallest even value are found return the node that has smallest index.
The plucked node should be returned in an array, [ smalest_value, its index ],
If there are no even values or the given array is empty, return [].
Example 1:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 2:
Explanation: 2 has the smallest even value, and 2 has the smallest index.
Example 3:
Example 4:
Explanation: 0 is the smallest value, but there are two zeros,
so we will choose the first zero, which has the smallest index.
Constraints:
* 1 <= nodes.length <= 10000
* 0 <= node.value
pluck(arr: [4, 2, 3]) == [2, 1]
pluck(arr: [1, 2, 3]) == [2, 1]
