097. trace tables: playing computer to find logic errors (ks4)
Develop advanced debugging skills by learning how to use trace tables to track variables, play computer, and hunt down hidden logic errors.
What do you do when your code runs perfectly but gives you the completely wrong answer? This is called a logic error, and they are notoriously difficult to find. To hunt them down, you have to "play computer". We will learn how to use trace tables to manually track the value of every single variable line-by-line, exposing the hidden flaws in your algorithmic logic.
