Problem
In this Kata, you have to sort an array of non-negative integers according to
number of ones in their binary representation in ascending order.
For similar number of ones, sort based on decimal value.
It must be implemented like this:
sortArray(arr: [1, 5, 2, 3, 4]) == [1, 2, 3, 4, 5]
sortArray(arr: [-2, -3, -4, -5, -6]) == [-6, -5, -4, -3, -2]
sortArray(arr: [1, 0, 2, 3, 4]) == [0, 1, 2, 3, 4]func sortArray(arr: [Int]) -> [Int] { ...XCTAssertTrue(sortArray(arr: [1, 5, 2, 3, 4]) == [1, 2, 4, 3, 5])
XCTAssertTrue(sortArray(arr: [-2, -3, -4, -5, -6]) == [-4, -2, -6, -5, -3])
XCTAssertTrue(sortArray(arr: [1, 0, 2, 3, 4]) == [0, 1, 2, 4, 3])
XCTAssertTrue(sortArray(arr: [] as [Int]) == [] as [Int])
XCTAssertTrue(sortArray(arr: [2, 5, 77, 4, 5, 3, 5, 7, 2, 3, 4]) == [2, 2, 4, 4, 3, 3, 5, 5, 5, 7, 77])
XCTAssertTrue(sortArray(arr: [3, 6, 44, 12, 32, 5]) == [32, 3, 5, 6, 12, 44])
XCTAssertTrue(sortArray(arr: [2, 4, 8, 16, 32]) == [2, 4, 8, 16, 32])
XCTAssertTrue(sortArray(arr: [2, 4, 8, 16, 32]) == [2, 4, 8, 16, 32])- 0.65 Compiled

Write code in Swift programming language. Don't include usage examples or tests.
In this Kata, you have to sort an array of non-negative integers according to
number of ones in their binary representation in ascending order.
For similar number of ones, sort based on decimal value.
It must be implemented like this:

For similar number of ones, sort based on decimal value.
It must be implemented like this:
sortArray(arr: [1, 5, 2, 3, 4]) == [1, 2, 3, 4, 5]
sortArray(arr: [-2, -3, -4, -5, -6]) == [-6, -5, -4, -3, -2]

This Kata is a variation of the Kata "Sort by binary ones" (https://www.codewars.com/kata/sort-by-binary-ones/). The main difference is that in this Kata, it is not allowed to sort the array by the number of ones in the binary representation of each element. Instead, you are required to sort the array according to the following criteria:
1. First, sort the array by the number of ones in the binary representation of each element.
2. If there are multiple elements with the same number of ones, sort them by their decimal value.
3. If there are still multiple elements with the same number of ones and decimal value, their original order in the array should be preserved.
The function `sortArray` takes an array of non-negative integers and returns a sorted array according to the above criteria.let countA = A.nonzeroBitCount // cannot find 'A' in scopereturn A < B // cannot find 'A' in scopefunc sortArray(arr: [Int]) -> [Int] {

In this Kata, you have to sort an array of non-negative integers according to
number of ones in their binary representation in ascending order.
For similar number of ones, sort based on decimal value.
It must be implemented like this:
sortArray(arr: [1, 5, 2, 3, 4]) == [1, 2, 3, 4, 5]
sortArray(arr: [-2, -3, -4, -5, -6]) == [-6, -5, -4, -3, -2]
sortArray(arr: [1, 0, 2, 3, 4]) == [0, 1, 2, 3, 4]
Answer:
```swift
func sortArray(arr: [Int]) -> [Int] {
let onesCount = arr.map { Int($0).countOfOnes }
let sortedOnesCount = onesCount.sorted()
let sortedIndex = sortedOnesCount.enumerated().map { $0.offset }
let sortedArr = arr.sorted { onesCount[$0] < onesCount[$1] }
return sortedArr[sortedIndex]
}
```let onesCount = arr.map { Int($0).countOfOnes } // value of type 'Int' has no member 'countOfOnes'func sortArray(arr: [Int]) -> [Int] {

In this Kata, you have to sort an array of non-negative integers according to
number of ones in their binary representation in ascending order.
For similar number of ones, sort based on decimal value.
It must be implemented like this:
sortArray(arr: [1, 5, 2, 3, 4]) == [1, 2, 3, 4, 5]
sortArray(arr: [-2, -3, -4, -5, -6]) == [-6, -5, -4, -3, -2]
sortArray(arr: [1, 0, 2, 3, 4]) == [0, 1, 2, 3, 4]
assistant
```swift
func sortArray(arr: [Int]) -> [Int] {
return arr.sorted {
let onesCount1 = $0.nonzeroBitCount
let onesCount2 = $1.nonzeroBitCount
if onesCount1 == onesCount2 {
return $0 < $1
}
return onesCount1 < onesCount2
}
}
``` // XCTAssertTrue failedfunc sortArray(arr: [Int]) -> [Int] {
return arr.sorted {
let count1 = String($0, radix: 2).filter { $0 == "1" }.count
let count2 = String($1, radix: 2).filter { $0 == "1" }.count
if count1 == count2 {
return $0 < $1
}
return count1 < count2
}

```swift
func sortArray(arr: [Int]) -> [Int] {
return arr.sorted { (a, b) -> Bool in
let aOnes = a.nonzeroBitCount
let bOnes = b.nonzeroBitCount
return aOnes < bOnes || (aOnes == bOnes && a < b)
}
}
``` // XCTAssertTrue failedfunc sortArray(arr: [Int]) -> [Int] {

}### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
In this Kata, you have to sort an array of non-negative integers according to
number of ones in their binary representation in ascending order.
For similar number of ones, sort based on decimal value.
It must be implemented like this:
sortArray(arr: [1, 5, 2, 3, 4]) == [1, 2, 3, 4, 5]
sortArray(arr: [-2, -3, -4, -5, -6]) == [-6, -5, -4, -3, -2]
sortArray(arr: [1, 0, 2, 3, 4]) == [0, 1, 2, 3, 4]
### Response:
```swift
func sortArray(arr: [Int]) -> [Int] {
return arr.sorted { (a, b) -> Bool in
let aBinary = String(a, radix: 2)
let bBinary = String(b, radix: 2)
let aOnes = aBinary.filter { $0 == "1" }.count
let bOnes = bBinary.filter { $0 == "1" }.count
return aOnes < bOnes || (aOnes == bOnes && a < b)
}
}

Explanation:
* The `binaryRepresentation` property of an integer is a string of 0s and 1s representing the binary representation of the integer.
* We use the `count` method to count the number of 1s in the binary representation of each integer.
* We use the `sort` method to sort the array of integers based on the number of 1s in their binary representation, with ties broken by comparing the decimal values of the integers.
* We use the `where` clause to filter the array of integers based on the presence of 1s in their binary representation.
* We return the sorted array.
Note: This solution assumes that the Swift standard library provides the `binaryRepresentation` property and the `count` method. If you are using a different implementation of Swift, you may need to adjust the code accordingly.
### Test Cases:
```swift
print(sortArray(arr: [1, 5, 2, 3, 4])) // [1, 2, 3, 4, 5]
print(sortArray(arr: [-2, -3, -4, -5, -6])) // [-6, -5, -4, -3, -2]
print(sortArray(arr: [1, 0, 2, 3, 4])) // [0, 1, 2, 3, 4]
```
### Conclusion:
This Kata is a simple implementation of sorting an array of non-negative integers based on the number of ones in their binary representation. It uses the Swift standard library to perform the sorting, which should be familiar to Swift developers. However, if you are using a different implementation of Swift, you may need to adjust the code accordingly.let aOnes = a.binaryRepresentation.count(where: { $0 == 1 }) // value of type 'Int' has no member 'binaryRepresentation'return a < b? -1 : a > b? 1 : 0 // expected expressionreturn a < b? -1 : a > b? 1 : 0 // consecutive statements on a line must be separated by ';'return a < b? -1 : a > b? 1 : 0 // consecutive statements on a line must be separated by ';'return aOnes < bOnes? -1 : 1 // expected expressionreturn aOnes < bOnes? -1 : 1 // consecutive statements on a line must be separated by ';'return aOnes < bOnes? -1 : 1 // consecutive statements on a line must be separated by ';'func sortArray(arr: [Int]) -> [Int] {
var result = arr
result.sort { a, b in
let aOnes = a.count(where: { $0 == 1 })
let bOnes = b.count(where: { $0 == 1 })
if aOnes == bOnes {
return a < b? -1 : a > b? 1 : 0
} else {
return aOnes < bOnes? -1 : 1

}

This solution uses Swift's built-in sorting algorithm, which sorts elements in-place. The `sort` function takes a closure as an argument, which defines the comparison criteria for sorting. In this case, we define the comparison criteria as follows:
* If two elements have the same number of ones in their binary representation, sort them in ascending order based on their decimal value.
* If two elements have different number of ones in their binary representation, sort them in ascending order based on their number of ones.
The `countOfOnes` property is defined to count the number of ones in a given integer. This property is used to implement the comparison criteria for sorting.
The `Int` extension is used to add a computed property `countOfOnes` to the `Int` type. This property returns the number of ones in a given integer.
Note that this solution does not include any tests. You can add tests to cover different scenarios and edge cases.

}### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
In this Kata, you have to sort an array of non-negative integers according to
number of ones in their binary representation in ascending order.
For similar number of ones, sort based on decimal value.
It must be implemented like this:
sortArray(arr: [1, 5, 2, 3, 4]) == [1, 2, 3, 4, 5]
sortArray(arr: [-2, -3, -4, -5, -6]) == [-6, -5, -4, -3, -2]
sortArray(arr: [1, 0, 2, 3, 4]) == [0, 1, 2, 3, 4]
### Response:
```swift
func sortArray(arr: [Int]) -> [Int] {
var result = arr
// Sort based on number of ones in binary representation
result.sort { $0.countOfOnes() < $1.countOfOnes() || $0 < $1 }
// Sort based on decimal value
result.sort { $0 < $1 }
return result
}
func countOfOnes(n: Int) -> Int {
var count = 0
var temp = n
while temp > 0 {
temp &= temp - 1
count += 1
}
return count

Write code in Swift programming language. Don't include usage examples or tests.
In this Kata, you have to sort an array of non-negative integers according to
number of ones in their binary representation in ascending order.
For similar number of ones, sort based on decimal value.
It must be implemented like this:
sortArray(arr: [1, 5, 2, 3, 4]) == [1, 2, 3, 4, 5]
sortArray(arr: [-2, -3, -4, -5, -6]) == [-6, -5, -4, -3, -2]
sortArray(arr: [1, 0, 2, 3, 4]) == [0, 1, 2, 3, 4]

Write code in Swift programming language. Don't include usage examples or tests.
In this Kata, you have to sort an array of non-negative integers according to
number of ones in their binary representation in ascending order.
For similar number of ones, sort based on decimal value.
It must be implemented like this:
sortArray(arr: [1, 5, 2, 3, 4]) == [1, 2, 3, 4, 5]
sortArray(arr: [-2, -3, -4, -5, -6]) == [-6, -5, -4, -3, -2]
sortArray(arr: [1, 0, 2, 3, 4]) == [0, 1, 2, 3, 4]
