Moser–de Bruijn sequence

A Moser–de Bruijn sequence is a type of pattern called a sequence of numbers. It's like a special code that is used to count from 1 to a very large number. Think of it like a sequence of numbers where each number can be thought of as the letter in a really really really long word. The Moser–de Bruijn sequence helps us figure out when to go to the next "letter" in the sequence so we can keep counting up to the biggest number possible.
