filterByPrefix(strings: ["abc", "bcd", "cde", "array"], prefix: "a") == ["abc", "array"]

Answer:
```swift
func filterByPrefix(strings: [String], prefix: String) -> [String] {
    return strings.filter { $0.hasPrefix(prefix) }
}
```

This function uses the `filter` method of the `Array` type to create a new array that only contains strings that start with the given prefix. The `hasPrefix` method is used to check if each string in the input array starts with the specified prefix.

    return strings.filter { $0.hasPrefix(prefix) }

This function takes an array of strings and a prefix string, and returns a new array containing only the strings that start with the given prefix. The comparison is case-sensitive.

This function uses the `filter` method provided by Swift's array to iterate over each string in the input array and checks if it starts with the given prefix. If it does, the string is included in the resulting array. The function returns the filtered array of strings.

```

This function takes an array of strings and a prefix, and returns a new array containing only the strings that start with the given prefix. The function uses the `filter` method to iterate over the array and select the strings that start with the given prefix.

Note: The function assumes that the input array contains strings. If the array contains non-string elements, the function may not compile or behave as expected.

func filterByPrefix(strings: [String], prefix: String) -> [String] {
    return strings.filter { $0.hasPrefix(prefix) }

This function takes an array of strings and a prefix, and returns a new array containing only the strings that start with the given prefix. The comparison is case-sensitive.

The function uses the `filter` method of the `Array` type to create a new array that only includes strings that start with the specified prefix.

Note: The function assumes that the input array contains only strings. If the array contains other types, the function may not compile.

This function takes an array of strings and a prefix, and returns a new array containing only the strings that start with the given prefix. The prefix is case-sensitive.

The function uses the `filter` method of the `Array` type to iterate over each string in the input array and checks if it starts with the given prefix. If it does, the string is included in the resulting array.

In the example usage, the function is called with the input array ["apple", "banana", "apricot", "cherry"] and the prefix "ap", and the resulting array is printed.

This function takes an array of strings and a prefix, and returns a new array containing only the strings that start with the given prefix. The comparison is case-sensitive.

The function uses the `filter` method of the array to iterate over each string and check if it starts with the given prefix. If it does, the string is included in the returned array.

In the example usage, the function is called with the prefix "ap" and the array of strings ["apple", "banana", "apricot", "cherry"]. The function filters out only the strings that start with "ap" and returns the resulting array, which is ["apple", "apricot"].

Filter an input array of strings only for ones that start with a given prefix.
filterByPrefix(strings: [] as [String], prefix: "a") == [] as [String]
filterByPrefix(strings: ["abc", "bcd", "cde", "array"], prefix: "a") == ["abc", "array"]
### Response:
```swift

    return strings.filter { $0.hasPrefix(prefix) }
}

print(filterByPrefix(strings: ["abc", "bcd", "cde", "array"], prefix: "a")) // ["abc", "array"]

Filter an input array of strings only for ones that start with a given prefix.
filterByPrefix(strings: [] as [String], prefix: "a") == [] as [String]
filterByPrefix(strings: ["abc", "bcd", "cde", "array"], prefix: "a") == ["abc", "array"]
### Response:
```swift
func filterByPrefix(strings: [String], prefix: String) -> [String] {
    var filteredStrings = [String]()
    for string in strings {
        if string.hasPrefix(prefix) {
            filteredStrings.append(string)
        }
    }
    return filteredStrings
}
```
### Explanation:
This function takes an array of strings and a prefix as input. It creates an empty array to store the filtered strings and then loops through the input array. For each string, it checks if it starts with the given prefix. If it does, the string is added to the filteredStrings array. Finally, the filteredStrings array is returned.

### Test:
```swift
print(filterByPrefix(strings: ["abc", "bcd", "cde", "array"], prefix: "a")) // ["abc", "array"]
print(filterByPrefix(strings: ["apple", "banana", "cherry"], prefix: "a")) // ["apple"]
print(filterByPrefix(strings: ["1abc", "2bcd", "3cde", "4array"], prefix: "1")) // ["1abc"]
```
### Conclusion:
This function works by creating an empty array to store the filtered strings, then looping through the input array. For each string, it checks if it starts with the given prefix. If it does, the string is added to the filteredStrings array. Finally, the filteredStrings array is returned. This function can be useful for filtering an array of strings based on a given prefix.

```
### Explanation:
The function `filterByPrefix` takes two arguments: an array of strings `strings` and a prefix `prefix`. It creates an empty array `filteredStrings` and then loops through each string in `strings`. For each string, it checks whether it starts with the prefix `prefix`. If it does, the string is added to the `filteredStrings` array. Finally, the function returns the `filteredStrings` array.

The first line of the function initializes an empty array `filteredStrings`. This is done because the function will return a new array containing only the strings that start with the given prefix.

The second line of the function uses a `for` loop to iterate through each string in the `strings` array. For each string, the function checks whether it starts with the prefix `prefix`. If it does, the string is added to the `filteredStrings` array using the `append` method.

Finally, the function returns the `filteredStrings` array.

Note that the function does not include any usage examples or tests, as it is intended to be a pure function that takes in an array of strings and a prefix and returns a new array containing only the strings that start with the given prefix.

### Test Cases:
```swift
print(filterByPrefix(strings: [], prefix: "a")) // []
print(filterByPrefix(strings: ["abc", "bcd", "cde", "array"], prefix: "a")) // ["abc", "array"]
print(filterByPrefix(strings: ["bcd", "cde", "array"], prefix: "a")) // ["abc", "array"]
print(filterByPrefix(strings: ["bcd", "cde", "array", "bcd"], prefix: "a")) // ["abc", "array"]
```
### Conclusion:
In Swift, you can use the `filter` method to filter an array of elements based on a given condition. In this case, you can use the `hasPrefix` method to check whether each element starts with a given prefix. If it does, the element is included in the filtered array.

func filterByPrefix(strings: [String], prefix: String) -> [String] {
    var filteredStrings = [String]()
    for string in strings {
        if string.hasPrefix(prefix) {
            filteredStrings.append(string)
        }
    }
    return filteredStrings
}

The time complexity of this function is O(n), where n is the length of the input array.

### Explanation:
The function `filterByPrefix` takes two arguments: an array of strings `strings` and a prefix `prefix`. It creates an empty array `filteredStrings` and then iterates over each string in `strings`. For each string, it checks if it starts with the prefix using the `hasPrefix` method. If the string starts with the prefix, it is added to the `filteredStrings` array. Finally, the function returns the `filteredStrings` array.

### Test:

print(filterByPrefix(strings: ["apple", "banana", "cherry"], prefix: "a")) // ["apple"]

### Output:
```
["abc", "array"]
["apple"]
[]
```
### Conclusion:
In this challenge, we have written a function `filterByPrefix` in Swift that takes an array of strings and a prefix as input. The function returns a new array containing only the strings that start with the given prefix. The function uses a for loop to iterate over each string in the input array and check if it starts with the prefix. If the string starts with the prefix, it is added to the new array. The function also includes test cases to verify its correctness.
