I am able to solve problems in CodeChef Practice (easy) but many of these problems are very easy i.e. cakewalk and require no logic at all while others are easy and boring. It’s very difficult to open a problem, read its complete problem statement and then realize it is very simple. I want to solve some problems in the easy (or medium) section which are not very easy to solve and require some thinking and algorithms and a different idea and viewpoint. Could you suggest a few such problems?
