Swift Array Programming Exercises: Create a new array with the elements in reverse order of a given array of integers

Last update on December 21 2024 10:28:49 (UTC/GMT +8 hours)

Write a Swift program to create a new array with the elements in reverse order of a given array of integers .

/*Given an array of ints length 3, return a new array with the elements in reverse order, so {1, 2, 3} becomes {3, 2, 1}.*/

Sample Solution:

Swift Code:

import Foundation
func reverse3(_ nums: [Int]) -> [Int] {
    return [nums[2], nums[1], nums[0]]
}
print(reverse3([1, 2, 3]))
print(reverse3([5, 11, 9]))
print(reverse3([7, 0, 0]))
print(reverse3([2, 1, 2]))
print(reverse3([1, 2, 1]))
print(reverse3([2, 11, 3]))
print(reverse3([0, 6, 5]))
print(reverse3([7, 2, 3]))

Sample Output:

[3, 2, 1]
[9, 11, 5]
[0, 0, 7]
[2, 1, 2]
[1, 2, 1]
[3, 11, 2]
[5, 6, 0]
[3, 2, 7]
