What is STL ?

What is competitive programming, and Why should you care.

Competitive programming is one branch of a larger tree. This tree broadly depicts various fields that a student must know about.

An Introduction to Graph

Here we are not gonna discuss the definitions of graph and its algorithm we are just going to visualise what graph…

Complexity — It is not that complex

Complexity : Complexity of an algorithm is a measure of the amount of time and/or space required by an algorithm for an input of a given size (n).

In analysing an algorithm, rather than a piece of code, we will try and predict the number of…

Prime Numbers — Mysterious and Beguiling

All prime numbers except 2 are odd, this makes 2 the oddest prime.

There are 78498 prime numbers smaller than equal to 10⁶
