## loopIn mathematics, the term "loop" may refer to any of the following: - A knot or hitch that holds its form.
- A degenerate edge of a graph that joins a vertex to itself.
- A sequence of instructions that is repeated either a specified number
of times or until a particular condition prevails. Loops lie at the
heart of most computer programs. The most common type is the
**iterative loop**, signified by keywords such as*for*,*while*,*do*, and*repeat*, or their equivalent, in which a given set of instructions is repeated a specified number of times. The**recursive loop**is a more powerful construct that carries out a given set of instructions, typically including recursive calls with modified parameters back to the instruction set itself, until a terminating condition is met. Recursive algorithms solve problems by reducing them to smaller and smaller subproblems until a solution is found, reusing the same set of instructions as often as needed.
