How Can I Exit Multiple Nested For Loops in Programming?

Exiting Multiple Nested 'for' Loops with 'break': An Alternative to GOTO

Question:

Can you utilize the 'break' statement to leave multiple nested 'for' loops?

Answer:

Notably, the 'break' statement only exits the innermost 'for' loop. For exiting numerous nested loops simultaneously, an alternative approach is required.

One method involves the use of flags or sentinel values. For instance, you can define a flag that, when set to 'True,' indicates that all nested loops should terminate. Within each loop, you can check this flag and break accordingly.

Another technique is to leverage the 'continue' statement. By using the 'continue' statement within an outer loop, you can skip the remaining iterations of that loop and proceed to the next iteration. This approach allows you to exit multiple nested loops with a single 'continue' statement.
