  • Algorithms
    • Algorithms can be used for anything, not just computing
    • There are 3 simple constructs in algorithms
      • Iteration - a step or sequence of steps that are repeated until a condition is met
        • All iteration starts with a phrase like: DO WHILE or REPEAT UNTIL
      • Selection - a decision making path with two or more outcomes, most commonly yes/no
        • All selection steps start with certain statements like: IF, IF-THEN or IF-ELSE
    • Before answering any algorithm question, you should always look for two things
      • What data you have to work with provided by the question to answer the question
      • What information should the solution provide
    • Pseudocode is used to write an algorithm, it is basically very basic shortened English
