Write a MIPSzy subroutine, power, that accepts 2 arguments x and y and computes x^y. You can assume that x and y are both larger than 0. The main program passes the two parameters and receives the return value through the program stack. You can assume that x and y are both larger than 0. The main program passes the two parameters and receives the return value through the program stack.

Test your subroutine with the following program:

addi $t0, $zero, 5100

top: lw $t1, 0($t0) beq $t1, $zero, done addi $sp, $sp, -4 sw $t1, 0($sp) addi $t2, $zero,4 addi $sp, $sp, -4 sw $t2, 0($sp) addi $sp, $sp, -4 jal power lw $t3, 0($sp) sw $t3, 0($t0) addi $sp, $sp,12 addi $t0, $t0, 4 j top

power: *** Put your subroutine here

done:
