Please convert C program to MIPS main int u v w k u s0 v

Please convert C program to MIPS

main() { int u, v, w, k; // u -> $s0, v -> $s1, w -> $s2, k -> $s3;

u = 2; v = 3; w = 4;

k = sum_square(u, v, w);

return;

}

int sum_square(int x, int y, int z)

{ int x2, y2, z2; // x2 -> $s0, y2 -> $s1, z2 -> $s2;

x2 = x * x; y2 = y * y; z2 = z * z;

return x2 + y2 + z2; }
