This is my MIPS Assembly Program: its supposed to define two integer arrays that are pre-sorted and the same size (e.g., [3, 7, 9, 11, 15, 21] and [1, 4, 6, 14, 18, 19]) and a function merge that takes the two arrays and their sizes as inputs and makes a single array of twice the size of either input array that contains the elements of both arrays in ascending order. In the example arrays given, then output would be [1, 3, 4, 6, 7, 9, 11, 14, 15, 18, 19, 21].
