Basic structures of algorithms
The fundamental structures of algorithms are “sequence structures”, “selection structures”, and “repetition structures.” Through a combination
of these structures, it is possible to express complex algorithms.
(1)Sequence structures
A “sequence structure” represents a flow which is carried out in a particular order.

(2)Selection structures
A “selection structure” represents a flow through which processes are selected based on certain conditions.
