Swift Array Programming Exercises: Create a new array that is left shifted from a given array of integers

Last update on December 21 2024 10:29:57 (UTC/GMT +8 hours)

Write a Swift program to create a new array that is left shifted from a given array of integers. So [11, 15, 13, 10, 45, 20] will be [15, 13, 10, 45, 20, 11].

Sample Solution:

Swift Code:

func left_shift(array_nums: [Int]) -> [Int] {
    var new_array = array_nums
    
    
    for x in 1..<array_nums.count {
        new_array[x-1] = array_nums[x]
    }
    
    new_array[new_array.count-1] = array_nums[0]
    
    return new_array
}

print(left_shift(array_nums: [11, 15, 13, 10, 45, 20]))
print(left_shift(array_nums: [0, 1, 2])) 
print(left_shift(array_nums: [1, 2]))
print(left_shift(array_nums: [1])) 

Sample Output:

[15, 13, 10, 45, 20, 11]
[1, 2, 0]
[2, 1]
[1]
