c++ solution

following C code. int mideterm_test(int g, h, i, j) { int f; f = (g + h) - (i+j); return f;) Assume that: the arguments g, h, i, j are placed by the caller in $a0, $a1, $a 2, $a3; that f computed and stored in $50, and that the result is in $v0. Write missing piece of code that will assure correct stack handling and return from the function. Save ONLY necessary registers. midterm_test: (Instructions 1 go here) add $t0, $a0. $a1 add $t1, $a 2, $a3 sub $so. $t0,$t1 add $v0, $s. $zero (instructions 2 go here)
