please sir check my code iam getting one TLE
TLE in one case
Hi @pankajsingh add the lines
ios_base::sync_with_stdio(false);
cin.tie(NULL);
Just inside your main function OR use scanf and printf (Cstyle) instead of cin and cout
for faster I/O as the input can be very large and reading large input can take lot of time so you will need a faster method like scanf ( faster than cin) for taking an input
In case of any doubt feel free to ask 
If you got the answer mark your doubt as resolved
ios_base::sync_with_stdio(false); cin.tie(NULL); what these line means
these lines are used to achieve same speed as scanf and printf using cin and cout
This disables the synchronization between the C and C++ standard streams. By default, all standard streams are synchronized, which in practice allows you to mix C- and C++ -style I/O and get sensible and expected results. synchronizing let both worlds to share the same buffers. For example cout << “Hello”; printf(“World”); cout << “Ciao”;; without synchronization you’ll never know if you’ll get HelloCiaoWorld or HelloWorldCiao or WorldHelloCiao…
If you disable the synchronization, then C++ streams are allowed to have their own independent buffers, which makes mixing C- and C++ -style I/O an adventure thus as a side effect you get a faster input processing
I will suggest u to read this article to get the clear understanding on fast I/O
I hope I’ve cleared your doubt. I ask you to please rate your experience here
