#### 2D Array of Integers With Square Root Dimensions

Given an integer K, return a 2D array of integers with dimensions sqrt(K) X sqrt(K) whose elements span the sequence from 1 to K. K will always have an integer square root (so K= 4, 9, 16, 25, etc) Ex: Given 9, return [ [1, 2, 3] [4, 5, 6] [7, 8, 9] ]
