2 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. Start Process ① Process ② End (2)Selection structures A “selection structure” represents a flow through which processes are selected based on certain conditions. Start Condition False True Process ① End 175 Process ②
