Find it. Not able to submit the code

When i submitted my code, it is showing “wrong answer” for 3 test cases. Then I downloaded the test cases and ran my code on each test case and I am getting correct answer for each test case. Why is this happening?

My code: https://ide.codingblocks.com/s/251290
