All of us, even those who have never programmed, know that computers and computer systems need a program to do anything.\u00a0But programming doesn’t usually start with writing a program.\u00a0Before writing the program ,<\/strong>\u00a0it is necessary to define step by step what the program should do, which is\u00a0called step by step operation definition,\u00a0algorithm\u00a0design<\/a> .<\/p>\n

It can be said that those who know how to code, convert the algorithm into an executable program in computers.<\/p>\n

Although all programmers are familiar with algorithm writing, and many algorithm experts know a little bit of programming;\u00a0But at the specialized level, these two skills are far from each other.\u00a0That is, algorithm designers get help from programmers to implement their algorithms, and programmers go to experts in this field to design or improve their algorithms.<\/p>\n

Those who work in organizational environments can understand\u00a0the concept of algorithm<\/strong>\u00a0to a great extent by imagining business operational processes .<\/p>\n

The process that a letter or document goes through from reaching the secretariat to classification, review, reference, action, and archiving is considered an algorithm in the mental model of programmers, with successive steps and with a clear definition and clear priority and delay starting from a starting point. and they end at some point and may be repeated tens, hundreds and thousands of times.<\/p>\n

Students can probably understand and imagine the concept of algorithm well by reviewing the steps of multiplying two ten-digit numbers.<\/p>\n

Algorithm concept<\/h2>\n

To better explain the concept of the algorithm, it is better to divide it into two parts ”\u00a0pattern<\/strong>\u00a0” and ”\u00a0rhythm<\/strong>\u00a0” and examine them separately.<\/p>\n

The pattern<\/strong>\u00a0is the\u00a0model<\/strong>\u00a0, and the model is a form of the reality of the phenomena that is formed in the mind, and for detailed analysis, we take them out of the abstract state by putting them on paper or drawing them in software.<\/p>\n

Rhythm<\/strong>\u00a0is the same\u00a0process<\/a>\u00a0and the process is a set of regular steps to achieve and create a positive and specific output.<\/p>\n

In simpler terms, in fact, to design and implement an algorithm, we need to build a model, which is realized in the form of a process.\u00a0So it can be said that algorithms are process-oriented models for establishing order.<\/p>\n

Many of our personal tasks have specific algorithms and predetermined routines.\u00a0Sometimes, we unknowingly choose and use a certain algorithm.<\/p>\n

But when the scale of activities and problems become larger, we feel the need for algorithms more than ever.<\/p>\n

If you decide to stand next to four or five of your friends in order of height for a commemorative photo, you will probably be running an algorithm without consciously paying attention.\u00a0But if a line of a hundred students is to be arranged in order of height, here we all feel that the algorithm should be defined clearly and precisely.\u00a0We can even compare and classify several different algorithms for this purpose based on specific criteria.<\/p>\n

If you are not familiar with the algorithm and its concept before, it might be a good idea to think a little about sorting the students in order of height and how you would do it if it were you.<\/p>\n

In order to experience the complexities of algorithm design even in this simple example, you can consider the following two cases separately:<\/p>\n
