How is this possible ??

I am using fast I/O method in my code for SIMPLESUM problem and instead it is increasing my runtime by give me tle in some subtasks…!! what should i do ?? they have recommended in question to use fast I/O methods !

Your algorithm may still not be fast enough. Happened to me.

i got ac for some subtask before using I/O ,and later tle for same subtasks…!!

Then maybe your assumed fast i/o isn’t fast :stuck_out_tongue: P.S: The predefined methods of taking inputs in c worked fine for me, so no extra code is required for fast input/output

may be you are right @vsp4 , thanks :slight_smile:
