clear the map ?

https://www.codechef.com/viewsolution/34705198, ya I actually forget to do that but still I am getting TLE

why are you running output n times ? you just need to do that once in every test case.

you are taking one input and printing output of collected input so far.

Still their is WA in my code

no you are printing result out of test case loop?

if these blocks confuses you try making function like this

solve() { ... }

main () {
       int t; cin >> t;
       while (t--) solve();
}

yaa I changed it, but still WA

also i don’t think if your mapping keys are correct,

we need to categorize poitns on two ways .

  1. their intecept on x - axis ( x - y ) and,
  2. (distant of point ( 0 , x ) - coordinate with intercept on x - axis ( 0 , x- y ) ) mod c - > ( x - ( x - y ) ) % c,

here this ( x - ( x - y ) ) could also have been negatice so inorder too take its mod you would have to keep it multiplying with c until it is positive.

consider my submission for help : https://www.codechef.com/viewsolution/34638847

yup I made a error in the intercept part, thanks bro I got it now.
