Largest With Its Position

The third element of grades is read from input() as one integer with no prompt. Using a for loop, find the largest grade and the index where it first appears, keeping a counter variable that you increase by one on every pass so you always know the current index; then print Largest <value> at index <index>. When two elements tie, the earlier index wins, so compare with a strict greater-than. Input: one integer. Do not use max() or any list method.
