iterative Fibonacci

Assembly Language: MIPS; HW help, could someone please walk me through how to code this in MIPS?

Thank you

int fiblt (int n) if (n 0) return 0; if (n 1) return 1 int a 0; int b 1 int result 0; for (int i 2; i n; i++) result b a; a b; b result return result; When you complete this, you shoul the previous section. It should be faster
