Name (10 pts) The function countChars charstr chartarget) returns the number of times characters in target appear in str. For example: int countChars(char str, char target) countChars( abc abc abc", "a") 3 countChars("abc abc abc", "ab") 6 countChars("abe abc abc", "abcd")-9 Int count 0; while ("str) ( count +a isCharinStr(target, "str) str++ The C code for countChars is given to you in the box on right. The helper function isCharinStr(char *target, char c) returns 1 if c is present in target and O if not. return count; Finish the implement of countChars in MIPS below. countchars addiu $sp, sp, store onto the stack if needed addiu $so, $ zero, o # we'll store the count in Ss0 addiu $si, $ao, o addiu $82, $al, o loop: addiu $ao, $s2, 0 beq jal isCharInstr done: # Load from the stack if needed addiu $sp, $sp dr $ra
