PLEASE USE MIPS ASSEMBLY LANGUAGE (I USE MYPSIM) AS MY COMPILER

Write a function that computes the next state of a linear feedback shift register (LFSR) given the current state of the LFSR. The LFSR should satisfy the taps given by the following polynomial: x 24 + x 23 + x 21 + x 20 + 1 Your function should take the state as a 32-bit input parameter and return a 32-bit output value. Your main program for the function should call your LFSR function for the following input states and print the output state:
