// explanation

// eli5Complexity is like asking 'how hard is this puzzle?' Some puzzles are easy and quick to solve, like finding a toy in a small box [6][7]. Other puzzles are super hard and take forever, like finding one specific toy in a huge warehouse [6][7]. Scientists use special labels (like 'Big-O') to describe how hard different puzzles are [6].
