I need help in completing the following MIPS assignment. Comment your solution code in detail with output, please. Thanks in advance!

I give thumbs up for correct solutions.

This program asks the user for a string named string and two characters (one for original and one for new). It then replaces each instance of the character original found in string with the character new. It outputs the resulting string and the number of substitutions that were made. For example, if string was "sassy" original was 's' and new was p, the program would output the resulting string of pappy" and 3 as the number of substitutions, A MIPS assembly file substitute.s in assignment 2 directory contains the code to get the string and two characters for you. It then contains the commented-out C code to do the real work. You should translate the C code to MIPS and add syscalls to output the results
