can you explain about the concept nested for with an example and how it works?
A nested loop is a logical structure used in computer programming where two repeating statements are placed in a "nested" form, i.e., one loop is situated within the body of the other. In a nested loop, the first iteration of the outer loop causes the inner loop to execute. The inner loop then repeats for as many times as is specified. When the inner loop completes, the outer loop is executed for its second iteration, triggering the inner loop again, and so on until the requirements for the outer loop are complete.

Looping, and by extension nested looping, is a powerful construct in programming as it allows rapid sorting or insertion of large amounts of data in an efficient way. Solving problems in the business world often involves repeating an action over and over with hundreds, thousands, or even millions of items of data. Nested loops are therefore frequently used constructs in all kinds of computer programs in all types of industry.
