Consider the following C functions:

int f1(int a, int b) { while (a != b) { if(a > b) a = a - b; else b = b - a; } return a; } int f2(int a, int b) { while (b != 0) { int t = b; b = a % b; a = t; } return a; } int f3(int a, int b) { while (a != 0) { int t = a; a = b % a; b = t; } return b; }

- All 3 functions return same value for all positive inputs
- f1 and f2 return same value for all positive inputs but not f3
- For some positive input all 3 functions return different values
- f2 and f3 return same value for all positive inputs but not f1
