Write MIPS code to search through array X of word size unsigned integers to find

Question

Write MIPS code to search through array X of word size unsigned integers to find how many of the values are divisible by 4. Place the result is $s2 and print to screen. The array X ends with a zero. Include code that counts the number of ones in the binary number stored in $s2 from part A. Place the result in $s3. Print to screen. Example x: word 5,4,8,12,13,16,18,20,24,23,0 After execution $s2= 6 $s3 = 2 Printed to the screen: The number of values that are divisible by 4 = 6 The number of ones in the binary number = 2
