Americans throw the paper in every years write common example

The average American household throws away 13,000 pieces of paper (around 1 billion trees in total in USA) each year. Most in the form of packaging and junk mail.

Recursive control:

Recursive structures provide an alternative to the loop paradigm for implementing the repetition of activities. Whereas a loop involves repeating a set of instructions in a manner in which the set is completed and then repeated, recursion involves repeating the set of instructions as a subtask of itself.

Implementation

The binary search algorithm is similar to the sequential search in that each algorithm requests the execution of a repetitive process. However, the implementation of this repetition is significantly different. Whereas the sequential search involves a circular form of repetition, the binary search executes each stage of the repetition as a subtask of the previous stage. This technique is known as recursion.

Programming language or natural language

Natural languages (such as English, German, and Latin) are distinguished from formal languages (such as programming languages) in that the latter are precisely defined by grammars, whereas the former evolved over time without formal grammatical analysis.
