The program asks the user three yes/no questions and prints a different message depending on the answers: 1) It asks if the user is attending most course sessions, spending effort, and curious about computers. 2) It prints "You will PASS this course!" if the first two answers are yes. 3) It prints "You will DO WELL!" if all answers are yes. 4) It prints "You will FAIL this course!" if all answers are no.

1. Write a MIPS assembly language program that - asks and gets answers for following Y/N
questions: a. Are you attending most sessions of this course (Y/N) ? b. Are you spending
considerable effort for this course (Y/N) ? c. Are you curious about how does a computer work
(Y/N)? - Prints out "You will PASS this course!" if both answers to question a. AND b. are Y
"You will DO WELL!" if all answers are Y "You will FAIL this course!" if all answers are N.
Show test runs for each of the possible outputs.
This should compile and run on MARS.
