Generate Bingo Cards In MIPS Assembly Language (Using MARS) Assignment Solution

Instructions

Objective

Write a MIPS assignment to generate Bingo cards (using MARS).

Requirements and Specifications

In MIPS Assembly Language (Using MARS) do the following: Bingo Card Generator Write a program that will: prompt the user for the number of players (maximum of 2) prompt the user for the number of cards to generate for each player (maximum of 2) for each card for each player, generate a valid bingo card (4 columns and 4 rows) provide a menu for the user to select 1-which user/bingo card to display 2-to run a histogram on the bingo cards generated to see how many times each number between 1 and 75 appeared 3-exit I have a picture attached that will show the desired output. I would need a lot of comments throughout the code. Also as mentioned, programmer has to use MARS to make this program and should be in the format of data and text.
