I gave my first ever contest, after all the negatives i got a score of +381. I was able to solve problem A and i knew the approach of problem b but failed to solve it. However, today i up solved problem B correctly and i figured out the logic behind problem C1 but i still do not know how to code it. I solved both the problems using for loop and if else blocks and did not use anything else because i don't know anything else lol haha.

I will try to solve it or else look at the editorial.
