Read this for most common causes. Didn't look at your code but I would guess that you have problems with floating point numbers.

resubmitted your code with long long vs long (which is 32 bit). Now it goes to test 7

it still got WA so you have other bugs, but hopefully this helps

      because on some compilers, long is 64 bit (but this is very rare), most other compilers, long is be 32 bit. long long is guaranteed 64 bit.
