I got AC.Thank you!
That was a stupid mistake

I think my algorithm is right,but I got WA.
Could someone tell me why?please

A little speech about the problem:

I got at least 6 times WA for the given code ( in the previous post). I posted here bcz I didn't found any bug in my code. I hoped that I will get helped from the great helpers about my problem. But I failed to get help from others.
