Let's see how two children solve the XOR problem using a plain everyday example. I strongly recommend this method. I have taken very complex problems, broken them down into small parts to children's level, and often solved them in a few minutes. Then, you get the sarcastic answer from others such as Is that all you did? But, the sarcasm vanishes when the solution works over and over again in high-level corporate projects.
First, let's convert the XOR problem into a candy problem in a store. Two children go to the store and want to buy candy. However, they only have enough money to buy one pack of candy. They have to agree on a choice between two packs of different candy. Let's say ...
