Hashing trick

The Hashing Trick is a way to store information using numbers. It works by taking a word or piece of information, like your name, and turning it into a number. You can do this by taking all the letters of your name, adding them together, and then using a formula to turn that number into a different number. You can then use this number to store information about you. For example, if you want to store your age, you can use the number from the Hashing Trick to do that.
