Hello everyone, I wanted to ask which ide should I use for competitive programming. I program in python

Thanks in advance !!

Hello everyone, this is Aryan. I am new to this platform as well as competitive programming. I just wanted to ask all of you , how dou think a question on reading it.

I will give you an example. In the CodeChef In september Lunchtime. The Watermelon problem (link : https://www.codechef.com/LTIME88B/problems/WATMELON)

After reading the problem I started putting all kinds of condition and for loop and stuff but still wasn't able to get the right answer. After the competition got over, and I read the solutions. It was just finding the sum and figuring out weather its greater than 0.

That was so easy, but only if you get to think like that.

So I wanted to ask you guys how you think out of the box or rationally after you read the question.

Hello Everyone. This is Aryan here. I am new to this platform. I am finding that the questions here are very nice. I am aware of basic programming concepts. I had the following doubts:

1) What concepts should I learn in-order to be able to solve most of the problems ( what are the important concepts of Competitive Programming)

2) Can anyone recommend the complete track ( in the sense list of problems sorted in basic to advance order) which I should solve to be able to compete in various competitions and get a decent rank

3) Can anyone explain what is div1 what is div2 and what is div3

Thanks a lot in advance. I am 13 years old and so I have a lot of time. So I wants to master my concepts at this beginning stage.
