Fill in 2D Numpy array recursively, and compute execution times M is a 2D array with dimensions N x N where N is an integer. It is defined as follows: The first column is just the set of numbers 0, 1, ..., N-1. The first row of elements is zero. The rest of the array is computed via recursive formula in which the element is equal to the sum of (a) the one just above and also the element above and to the left. The figure below illustrates this: To compute the value of the element in the red oval,
