[Stage 34] Extract Each Kth

Given array of integers, remove each kth element from it.

Example

For inputArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] and k = 3, the output should be extractEachKth(inputArray, k) = [1, 2, 4, 5, 7, 8, 10].

Input/Output

• [execution time limit] 4 seconds (py3)

• [input] array.integer inputArray

Guaranteed constraints:
5 ≤ inputArray.length ≤ 15, -20 ≤ inputArray[i] ≤ 20.

• [input] integer k

Guaranteed constraints:
1 ≤ k ≤ 10.

[output] array.integer

inputArray without elements k - 1, 2k - 1, 3k - 1 etc.

def extractEachKth(inputArray, k):
    for i in range(len(inputArray)-1, -1, -1):
        if i % k == k-1:
            del inputArray[i]

    return inputArray
