Verifying the behavior of a loop can be tricky when you have no idea how many cycles it will complete. The secret is to establish a specific condition that is correct right from the beginning and is maintained throughout each individual cycle. Through the principle of induction, you can be confident that this characteristic will remain valid once the execution finally concludes. For a great demonstration of this method in action, @RaghavMalik15 breaks down exactly how LLEQ puts this into practice.
