Concept of algorithm.

Types of algorithms. Examples. Algorithm diagram.

The algorithm is a system of the formal rules which accurately and single-digit contour sequence of actions of enumerative process from initial data to required result. There are three basic structures of algorithm:

- The linear algorithms

The algorithm in which all stages of the solution of the task are executed strictly sequentially is called the linear. I.e. the linear algorithm is executed in a natural order of its writing and doesn't contain ramifyings and repetitions.

- Algorithms of branching structure

Algorithm of branching structure we will call such algorithm which one of several possible ways (options) of calculating process is selected. Sign of branching algorithm is existence of operations of the conditional branch when there is a check of truth of some logical expression (a checked condition) and depending on truth or falsehood of a checked condition for execution this or that branch of algorithm is selected

- Cyclic algorithm.

Implements repetition of some actions. Differently Cyclic algorithms include cycles. The sequence of the actions executed repeatedly, each time is called as a cycle in case of new parameter values.

unit of the beginning/the end, unit of input-output, unit of action, unit of logical action, unit of a cycle
