You are supposed to write a MIPS program to check validity of a user$-$inputted numerical

expression via MIPS simulator I$/$O window. The syntax for the expression should be based on

Matlab rules. Your program should display the prompt $">"$ for entering an expression of up to

$64$ symbols. Expressions should include only parentheses $(),$ digits from $0$ to $9,$ and operators $+,$

$-,*,/$ and spaces. If there is error in an expression, display "Invalid input" in the I$/$O window; if

there is no error, display "Valid input" in the I$/$O window.

Your program should loop so that users can enter new expressions without re$-$assembling the

program. Your code should be commented. I need the full code. Might be around $200$ lines of code or more and please make sure output is correct
