Diversity of applications

Do you remember all of the data structures shown in the book? Due to the high number of described topics, it is a good idea to take a look at the following data structures once more, together with their associated algorithms, just in the form of a brief summary with information about some real-world applications.

Arrays

Let's start with arrays, which is one of the two main topics in the first chapter. You can use this data structure to store many variables of the same type, such as int, string, or a user-defined class. The important assumption is that the number of elements in an array cannot be changed after initialization. Moreover, arrays belong to random access data structures, which...
