Write a MIPS assembly program that solves the following problem. Ask the user to enter 4 unsigned (positive) 32-bit integers. Read these 4 integers; let's call them A, B, C, D. At the end of your program, registers $t8 and $t9 should contain the 64-bit result of ((A*B) + (C*D)); $t8 should have the most significant 32 bits and $t9 should have the least significant 32 bits.
