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 * it displays the words “Give a number” and waits for the player’s answer * it compares the player’s answer with the drawn number: * if the number does not match * it checks if the number given by the player is higher than the randomly selected number * if it is * it displays the message: “Too high!” * otherwise * it displays the message “Too low!” * once again it prompts the player, waits for an answer and compares it with the drawn number * 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.
