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 develop a program that finds how many times a word is used in a given statement. To test your program, you should hardcode the below sample statement in your code, and ask user to input two different words, which are "UCF" and "KNIGHTS" in this project, however your code should work for any words with less than 10 characters. Your program should not be case sensitive and regardless of the way user inputs the words it should correctly find the words.

Sample Statement: UCF, its athletic program, and the university's alumni and sports fans are sometimes jointly referred to as the UCF Nation, and are represented by the mascot Knightro. The Knight was chosen as the university mascot in 1970 by student election. The Knights of Pegasus was a submission put forth by students, staff, and faculty, who wished to replace UCF's original mascot, the Citronaut, which was a mix between an orange and an astronaut. The Knights were also chosen over Vincent the Vulture, which was a popular unofficial mascot among students at the time. I11 1994, Knightro debuted as the Knights official athletic mascot.

Sample Output: Please input first word: Knight (or KnIGhT, knight, ...) Please input second word: UCF (or ucf, UcF, ...)

KNIGHT: - 6
UCF: 3
