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

# Bubble sort
For each element starting from the first, compare with the adjacent element and swap the two if they are in incorrect order, i.e., `arr[i] > arr[i+1]`. The first iteration places the largest element at `arr[N-1]`. The second iteration places the second largest at `arr[N-2]` and so on…


* Initially:[6 3 5 4 1 2]
* Iteration 1: [**6 3** 5 4 1 2] -> [3 **6 5** 4 1 2] -> [3 5 **6 4** 1 2] -> [3 5 4 **6 1** 2] -> [3 5 4 1 **6 2**] -> [3 5 4 1 2 6]
* Iteration 2: [**3 5** 4 1 2 6] -> [3 **5 4** 1 2 6] -> [3 4 **5 1** 2 6] -> [3 4 1 **5 2** 6] -> [3 4 1 2 5 6]
* Iteration 3: [**3 4** 1 2 5 6] -> [3 **4 1** 2 5 6] -> [3 1 **4 2** 5 6] -> [3 1 2 4 5 6]

For example, in the third iteration, we can stop after the first four elements because the previous two iterations will make sure the last two elements are larger than the first four elements.

In this lesson, we'll learn how bubble sort works and see the implementation.
