34. extracntEachKth

Task

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.

My Solution

def extractEachKth(inputArray, k):
    del inputArray[k - 1::k]
    return inputArray
