(a) [10 marks] Write a MIPS assembly langugge function (called Countzero) that accepts a binary number in register $a0 and retums a value corresponding to the number of zero's in the binary number in 5v0. (b) [10 marks] Translate the following pseudocode expression to MIPS assembly language code. Include code to insure that there is no array bounds violation when the store word (sw) instruction is executed. Note that the array "zap" is an array containing 50 words, thus the value in register $a0 must be in the range from 0 to 196. Include code to insure that the value in register $a0 is a word address offset into the array "zap." If an array bounds violation is detected or the value in register $a0 is not a word address offset then branch to the label "Error". .data zap: space 200 text zap[$a0]=$s0
