What is iterate?

Iteration is a programming technique in which a set of instructions are repeatedly executed until a specified condition is met. It is used to traverse or iterate over a set of data points, such as a list, array, or string, and perform some operation on each element in the set.

The most commonly used forms of iteration in programming are:

1. For loop: This loop is used when the number of iterations required is known beforehand. It executes a block of code repeatedly, each time incrementing or decrementing a loop counter until a certain condition is met.

2. While loop: This loop is used when the number of iterations required is not known beforehand. It executes a block of code repeatedly, as long as a certain condition is true.

3. Do-while loop: This loop is similar to the while loop, but it executes the block of code at least once, even if the condition is initially false.

Iterating over data structures is a fundamental concept in programming and is used in a wide range of applications, such as searching, sorting, and processing data.
