Write a MIPS program that has two procedures.The first procedure is tolower to convert a null terminated string to all lowercase. Do not convert characters that are already lowercase. Count the number characters that you convert to lowercase. Pass the memory location of the from string to convert in $a0. Pass the memory address of the string to copy the converted string into in $a1. Return the number of characters that were translated in $v0. The second procedure is toupper to convert a null terminated string to all uppercase. Do not convert characters that are already uppercase. Count the number of characters that you convert to uppercase. Pass the memory location of the from string to convert in $a0. Pass the memory address of the string to copy the converted string into in $a1. Return the number of characters that were translated in $v0. In your mainline, Ask the user for a string to convert to lowercase. Print the converted string and the number to characters translated. Ask the user for a string to convert to uppercase. Print the converted string and the number to characters translated.

Example output:

Enter a string to convert to lowercase: Hello World. I am 100 years old!

The converted string is: hello world. i am 100 years old!

The number of translations is: 3

Enter a string to convert to uppercase: Hello World. I am 100 years old!

The converted string is: HELLO WORLD. I AM 100 YEARS OLD!

The number of translations is: 18

This is what I have it only converts one character to lowercase, I wanted to make sure that worked before trying my loop.I'm not sure how the loop should be written, or how to correctly do the translations.
