Write a well-documented MIPS Assembly program (minimum number of instructions), that defines four variables: xa, ya, xb and yb of integer type initialized with any values. Then prompts the user to enter from the KBD one character ("Y" or "N"), calculates the value off as shown below, and prints the values of all given variables and calculated value of f at the beginning of a new line separated by tabs. ((xa - xb)? (ya - xb) if the user enters "Y" (xa xb)2 / (ya -- xb) if the user enters "N" Hints & Notes: Assignments must be prepared and submitted by teams of No more than two students. Late submissions are NOT accepted. Write and test the code for calculating fand debug it before moving to calculating the second equation, Use simple values to verify the correctness of calculations in your program. Practice well with ALL buttons and commands to work with MARS software. Use single-step mode to watch the contents of registers and memory locations after executing each instruction. Repeat the previous steps with new values of variables
