I am not able to run on the compiler and also showing me nzec error and I think my code is fine as it works on other compilers.
note : I know I have to give custom input and I am giving it perfect
pls do something.


Which problem? Can you send a screenshot?

my code is right but i’m getting WA. I submitted it 7 times still wrong.
FFL div 2

Submitting the same code doesn’t change the verdict.


every time a different solution, approach is same only way of code is different.

Then, there must be flaw in your logic…try to think more.

and i submitted the solution of second question but it somehow got submitted in 1st one.

i’m pretty sure my logic is correct.

Must have clicked on the wrong link.
