Question: In MIPS (Mars), How to write a program that if the user inputs a Hex number (e.g. 0xDEADBEEF) translates the string into a binary integer

In MIPS (Mars), How to write a program that if the user inputs a Hex number (e.g. 0xDEADBEEF) translates the string into a binary integer (in twos complement format), then stores this result in the ($s0), then convert this signed integer into an ASCII decimal representation , printout like (e.g. -559038737). You can not use any syscall whose description begins with read.
