Translate the following procedure/function into a MIPS assembly code. Assume that the array's base is in register $a0, and the array's length is stored in register $a1. Properly return the function result and ensure that your MIPS code can go back to the location from where the function is called.

func diff_sum(array, length) {

int result = 0

for (int i = 0; i < length; i++) {

if (i % 2 == 0) {

result = result array[i];

} else {

Result = result + array[i];

}

}

return result;

}
