Multithreading support was introduced in C+11. Prior to C++11, we had to use POSIX threads or p threads library in C. While this library did the job the lack of any standard language provided feature-set caused serious portability issues. C++ 11 did away with all that and gave us std::thread. The thread classes and related functions are defined in the thread header file.

std::thread is the thread class that represents a single thread in C++. To start a thread we simply need to create a new thr...

A skip list is a probabilistic data structure. The skip list is used to store a sorted list of elements or data with a linked list. It allows the process of the elements or data to view efficiently. In one single step, it skips several elements of the entire list, which is why it is known as a skip list.

Sorting refers to arranging data in a particular format. Sorting algorithm specifies the way to arrange data in a particular order. Most common orders are in numerical or lexicographical order.

The importance of sorting lies in the fact that data searching can be optimized to a very high level, if data is stored in a sorted manner. Sorting is also used to represent data in more readable formats. Below we see five such implementations of sorting in python.

• Bubble Sort
• Merge Sort
• Insertion Sort
• Shel...

How to Run

## Conventional Run
~/package $ mkdir build
~/package $ cd build
~/package/build $ cmake ..
~/package/build $ make

## Single Line CMake build
~/package/ $ cmake -S project -B build -G "MinGW Makefiles"
~/package/ $ make -C build
~/package/ $ build\MyExample

Once cmake build has been called, we can edit files and directly run them using

~/package/ $ make -C build && build\MyExample
