# Student: Zhenxing He # Description: recursiveFunction.asm - This program uses recursive function to find the smallest integer in a given array. # The given array A = {5, 2, -9, 10, -23, 43, 2, 1, 3, 5, 10}, low( the first index of array A) = 0, # high( the last index of array A ) = 10 .data A: .word 5, 2, -9, 10, -23, 43, 2, 1, 3, 5, 10 str: .asciiz "The minimum of array A is:\n" .text .globl main main: la \$a0, A li \$a1, 0 # low li \$a2, 10 #high jal Min move \$t5, \$v0 la \$a0, str li \$v0, 4 syscall move \$a0, \$t5 li \$v0, 1 syscall li \$v0, 10 syscall .text Min: bne \$a1, \$a2, RecursiveCall # branch if low != high sll \$a1, \$a1, 2 # low*4 add \$t1, \$a0, \$a1 # A+low lw \$v0, 0(\$t1) # load A[low] jr \$ra RecursiveCall: add \$t0, \$a1, \$a2 # low + high sra \$t0, \$t0, 1 # (low + high)/2 addi \$sp, \$sp, -16 sw \$ra, 0(\$sp) # back up the return address sw \$a1, 4(\$sp)

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
