How to sort the part of an array in Swift

Answer 1

import Foundation

var arr = [15, 6, 19, 8, 3, 7, 9, 1, 4]

// Extract the subrange (indices 2 to 6 inclusive)
let subrange = Array(arr[2...6]).sorted()

// Replace the original subrange with the sorted one
for (i, value) in subrange.enumerated() {
    arr[2 + i] = value
}

// Print the updated list
let formatted = arr.map { String($0) }.joined(separator: ", ")
print("[\(formatted)]")




/*
