I have complete knowledge of c++ with data structures and algorithms , which is the best site for me to start programming ?
for CP: codeforces, Atcoder
for Technical interviews: LEETCODE, INTERVIEWBIT
Codechef’s Long Challenges are the best for beginners. Most of my learning has taken place in those contests.
You can try spoj. It has most of the standard problems a beginner should know.
but i have heard , it starts getting tougher after 5-10 question is it true ?
geeksforgeeks? hows that
Not really 5-10 questions, but yes it is on the tougher side. But the problems are mostly standard. I don’t think there are direct standard questions of a concept on codeforces or atcoder.
ok and will it also help me in interview preparation ?
Sure. Also try leetcode for interviews preparation.
thanks for your help
Atcoder and Codeforces of course
it have great tutorials
