General question

sir I do not want to be pro competitive programmer but I want to practice some easy problems on one of the platforms ,but there are a lot of platforms
which is the best?
code forces, code chef ,sphere online judge ,ect?
so what is the best

you can start solving contest simultaneously.
it will boost your confidence simultaneously.
you will definitely able to solve questions then.
first complete your course .

there are plenty of websites for practicing questions like leetcode, codechef, codeforces, SPOJ, hackerearth, hackerrank, atcoder, the list goes on.
I find it best to participate in contests and upsolve the questions later, which I couldnt solve during the contest. You can pick any past contests too. If you want some topic specific questions, most of the questions have tags so you can search with the help of that.
After you are done with the question(solved it completely) you can also look at other’s submissions and editorial solutions to look for alternate approaches, or look on youtube for its solutions, you will often find great explanations.
Also geeksforgeeks is a great resource and it has articles for almost everything.
