Question

Write a MIPS code to arrange the given set of integers in descending order. You may either assume that the set of integers are provided as initialization of array elements (or) you may ask the user to input the set of integers. You must have the output as

The given integers arranged in descending order is

xx

yy

z

It would be helpful to post the code and corresponding output. Thanks!
