Write an ASCII character counter for an array in MIPS assembly language, using subrutines.

The starting address of the array of ASCII characters must be passed to the subroutine in $a0. The 32-bit unsigned length of the array of ASCII characters must be passed to the subroutine in $a1. The one byte ASCII character to search for must be passed to the subroutine in $a2.

If the value to search for is valid, the subroutine must count the number of times that the character appears in the supplied ASCII array and return it to the caller as a signed word in register $v0. If the value to search for is invalid , the subroutine must return the value -1 to the caller in register $v0.

The subroutine must preserve the values of the $sX registers, and it cannot use any values from the main program that are not explicitly passed to it as arguments.
