Project #$2$: Part A

Purpose of this project is to increase your understanding of data, address, memory contents, and strings. You will be expected to apply selected MIPS assembly language instructions, assembler directives and system calls sufficient enough to handle string manipulation tasks. You are tasked to find the number of selected letters present in a string. Specifically, the number of the occurrences of the letters K$,$ N$,$ I, G$,$ H$,$ T$,$ R$,$ and O $($upper and lower cases both to be counted$)$ within an input sentence, and then output the result using the format shown below:

Sample Input for Part A is:

In $1980,$ UCF decided to revamp the mascot to motivate the crowd and draw attention to the new football program. That brought the debut of Sir Wins$-$a$-$lot, a knight$-$themed mascot featuring a large smiling face made of plastic. Sir Wins$-$a$-$lot was eventually retired in favor of a horse and rider.

Sample output for Part A is:

$K$: $1$

$N$: $13$

I: $16$

$G$: $6$

$H$: $9$

$T$: $27$

$R$: $16$

$O$: $19$

Output a histogram of the number of the occurrences of the letters $K,N,$I,$G,H,T,R$ and $O$ within an input sentence:

K: #

$N$: ##############
