I need help programming a function in mips that will help me create a histogram. this is my current code but I need help with my output. My output is: 7,2,6

the number of unique values is:

0 0.

0 0.

0 0.

I need to count the numbers and how many times they appear.

hist:

add $t0, $zero, $zero #i = 0

add $t5, $zero, $zero #k = 0

hist_loop:

slt $t1, $t0, $a1

beq $t1, $zero, end_hist

sll $t1, $t0, 2

add $t1, $a0, $t1 #array a[i]

lw $t2, 4($t1) #array a[a + i]

beq $t1, $t2, counter

addi $t5, $t5, 1 #i++

addi $t0, $t0, 1 #k++

j hist_loop

counter:

subu $t5, $t5, 1

j hist_loop

end_hist:

move $v0, $t5 #return number of k values
