oneInEachSubArray

Define a function that when passed an integer array and a second integer representing the number of sub-arrays in which it should be divided (assume it can be divided evenly), returns true if there is at least one common item in every sub-array, false otherwise.

oneInEachSubArray([20, 20, 20, 20], 2) → true
oneInEachSubArray([20, 20, 20, 10, 10, 10], 2) → false
oneInEachSubArray([10, 70, 20, 90, 50, 80, 60, 10, 20, 10, 100, 70], 3) → true
