MIPS Password Hack Program

Your objective is to "hack" into other people's computers. The first step is to "break" the "firewall". In other words, my fellow students, you need to break down the password!

WHAT YOU NEED TO DO:

Please design a simple MIPS code to break down a six-digit integer password determined by user!

HINT: you could brutally break down the password, which tries every combination (at most 10^6 times).
