Write a MIPS assembly language program swapElements.s that will swap the contents of two elements of an array, given the array and the indices of the elements to be swapped. The indices should be read from the keyboard, not hard-coded. For the indices, use two more integer variables declared in the data section with .word. (Warning: you can't use `j' as a label/variable name, since j is an opcode). Print all of the elements of your array both before and after the swap, this will involve a loop.
