Definition Of Algorithm

• Algorithm is a sequence of logical steps of problem solving that are arranged systematically.
• The word logical here means true according to human logic.
• To be an algorithm, the sequence of steps taken to solve the problem must give the correct result.

Algorithm Writing

1. In natural language (Indonesian, English, and other human languages)
   • But often ambiguous
2. Using a flow chart (flow chart)
   • Good visually but bother if algorithm is long
3. Using pseudo-code
   • It is closer to the programming language, but it is difficult to understand by people who do not understand programming

Algorithm In Natural Language

• Take the first number and set maks equal to the first number
• Take the second number and compare it to the maks
• What if the second number is greater than the maks, the set maks equals the second number
• Take the third number and compare it to the maks
• If the third number is greater than the max, the set maks equals the third number
• The maks variable contains the largest number. Show the results

Example algorithm 1

1. There are 2 glasses. One contains tea and the other contains coffee. How do I change the contents of each glass?
   

The Answer

• Prepare backup glass X
• Pour glass of tea into glass X
• Pour a glass of coffee into a tea cup
• Pour a glass of X that contains tea into a coffee cup
