👉 Complexity is a measure of how difficult it is to solve a problem. It can be defined as the number of different ways that an algorithm or process can be broken down into simpler steps, and then solved in order. For example, if we have a program that takes 3 days to complete a task, but only requires 2 hours to complete the same task on a computer, the complexity of the program is high because it involves multiple steps. On the other hand, if we can solve
