The first algorithm version may look like this:
''After the programme has been started: ''
* it displays a message telling you how to play, e.g. “I thought of a number between 1 and 100. Guess what number it is!”
* it draws a number (in the range from 1 to 100) and stores in a variable
* if the number matches
* it displays “Well done!”
* it ends the script execution''
''After the first algorithm version has been written down we point out that we are dealing with certain actions which will be repeated.
