Gain insights into competitive programming, explore C++ skills with theory, code samples, practice problems, and master faster implementation for contests like ACM ICPC, Google CodeJam, and HackerCup.

Competitive programming can be a great way to build out your programming skills, get on any major company’s radar, and earn a little extra cash along the way.

In this course, you will learn to prepare for competitive programming contests like ACM ICPC, Google CodeJam, Facebook HackerCup, and many more.

Each topic is broken down with a healthy mix of theory, code samples, step-by-step solved sample problems, illustrations, useful practice problems, and tips and tricks for faster implementation.

You will need some solid C++ foundations coming into this course, but by the end it, you will be confident enough in your C++ skills to take home the win.

Competitive Programming in C++: The Keys to Success

# Algorithm
A new key is always inserted as a leaf. We search for the location for a new key as mentioned in the previous lesson and insert the new node when we reach the end.

**Time Complexity**: In the worst case, we traverse to the deepest node. So insertion time complexity is $O(height)$ or $O(N)$.

# Visualization

In this lesson, we'll see how to insert a new key in a BST.
