I was trying to submit this problem after ensuring the 4 test cases given in the problem, but I found it gives wrong answer in test 4. however, this test case I try it, and I'm sure my program output the correct answer
in the fourth test case
10 10
10 10
10 10
the answer is -1 and my program actually output -1, but in the submission it said my output is :
8 2
2 0
could anyone explain why !!
In this Editorial, problem C code, I saw constexpr for the first time, so I read about it in GeeksforGeeks, and what I understood is it's something for performance improvement of programs by doing computations at compile time rather than run time.
So I expected that submitting using constexpr will make the code faster, but I found the opposite!
This code 57476357 which using constexpr gets accepted in 30ms, and this code 57476398 without constexpr gets accepted in 15 ms
Is there any explanation for that cause I think that I have a misunderstanding here.
