a) Write a function called ArraySparse, which determines if a 2D array is sparse or not. We define a 2D array to be sparse if its number of zero elements is at least twice as large as the number of non-zero elements. The argument to the function is a 2D array, which is an array of pointers to each row. b) Declare and initialize an array of type int in main. Then utilize the above defined function to determine if the array is sparse or not sparse. As an example, you can choose an array of size 4 x 4
