The following problem: Your text to link here... requires DP + 2D BIT according to comment section but I have never used 2D BIT anywhere except for learning its basic concept. Can someone explain how to solve this problem using this concept? Thanks in advance.

I have written an article on how to implement lower_bound() function of C++ in Java by creating our own method and also using java inbuilt functions. Feel free to comment if you have any query.

Lets share the best meme related to programming we have!

Ps: I know its a bit old but still relatable.

My program is running in O(n) time (I hope so) but it is showing TLE in java. Can anyone please tell me what am I doing wrong here. I have used fast input with both BufferedWriter and PrintWriter but it is still showing tle. I know there is no problem with my logic because the same logic is accepted in C++. So can someone please tell me what is wrong with my java code.

Solution: Java: 82284306 CPP: 82285437

Problem: 1324D - Pair of Topics

Edit 2: The code worked after I replaced array with ArrayList. Can anyone explain to me why did this happen? Thanks in advance.

Many coders who like coding in Java for competitive coding have faced a “TLE” even though their logic and complexity are well within the bounds. The problem in those cases lies in our way of I/O. Using Scanner and System.out.println() in a code is quite convenient but often make our program slow. I am sharing my article in which I have shared my template. I urge fellow coders to check this out and please do notify me if anything can be improved. Thank You!
