You need help with MIPS Assembly Language and the MARS program development environment.
Demonstrate how to implement loops in MIPS. The program should read from memory the contents of an array containing an arbitrary number of characters, followed by a period (‘.').
Your program should create a second character array which is identical to the first, except that the case of every alphabetical letter has been changed:
for example, given the input string "Ab()Cd1234EfGh#.", your program would create the string "aB()cD1234eFgH#." and store it in a buffer. Test the program using input strings of different lengths.
The program may assume that the input string will always contain a single period, which will always be the last character.
