Understanding Iteration: A Key Concept in Programming and Problem-Solving

Iteration is a process of repeating a set of instructions multiple times, with each repetition called an iteration. The purpose of iteration is to perform a task multiple times, with each iteration refining or improving the previous one, until a desired result is achieved.

For example, in programming, you might use a loop to iterate over a list of items, performing some action on each item in the list. Each iteration of the loop would process one item from the list, and the loop would continue until all items have been processed.

In more general terms, iteration can refer to any process of repeating a set of steps, with each repetition building upon the previous one, until a desired outcome is achieved.
