    Your problem description is still quite vague. For starters, it lacks the definition of all those variables you're using.

    but comparision is not same.

    So how do they differ?

    But here's a hint: it's rather unlikely that Loop+1 is the index you should be using after the first loop. Re-check the semantics of the for loop with your textbook to see why.
