without using any native multiplication instructions, subroutines, and function calls. More formally, write MIPS assembly code that accepts four positive integers A$,$ B$,$ C$,$ and D as input parameters. The code shall execute in MARS to prompt the user to enter four positive integers represented in decimal, each separated by the Enter key. The program shall calculate f$=($A$\backslash$times C$-$B$\backslash$times B$)$ and g$=($B$\backslash$times C$+3\backslash$times D$)$ using your own self written multiplication routine. The program will then output f and g in decimal and binary, using syscall for each output.

What not to use: any of $\{$mul$,$ mul.d$,$ mul.s$,$ mulo, mulou, mult, multu, mulu, div, divu, rem, sll$,$sllv$,$ sra, srav, srl$,$ srlv$\}.$ The goal to compose your own division technique. In addition, use of a loop is required for credit to realize the multiplication code. Do not use Macros, Subroutines, or Functions in this project.
