These are not the reason for any Indian not present among red coders, the reason is, most of the youths who choose maths are mad about JEE, parents are crazy about JEE examination, and so, students never get an opportunity to explore anything related to coding or other fields.

Second reason is placement package, parents in India want their son/daughter to crack JEE just to get into IITs, so that they may get big fat money after graduation. Once some eligible candidate goes into IITs or other premier college, they get to know how worthless their efforts were just to get selected in a college. Although things are improving slowly but, JEE and coaching is killing creativity and time of many eligible students.

please someone help me in problem b. how can we change string 1st to 2nd with this test case: ac ab ?

Or award someone who caught someone cheating. We may even publicly tag that person here or on LinkedIn. That's the only punishment for such cheaters.

this year thaught me many things, gave me many experience, but the best thing i ever experienced was that happiness when my first solution was accepted on codeforces contest. hello every coders out here, i love you all.

why my name is not in final standing ? i have already participated in more than 2 rated contest and my rank is below 1600. i am new to competitive coding and this is really demotivating.. @vovoh please do consider.
