Sorting

Frequency: 10/10

Some points to note:

• Use built-in sort function (for example std::sort in C++) instead of writing your own sort function.
• Learn how to use custom comparator for sort function to sort user-defined data types (.i.e struct, class,etc) or to sort primary data types in a different way (for example, sort strings based on their last characters).
• Using Counting sort may lower time complexity.
