Explain what LiveLock is and how it differs from deadlock.

LiveLock is a situation where two or more processes constantly change their state in response to each other, but cannot make progress, even though resources are not blocked. Unlike deadlock, where processes wait for each other and cannot continue due to mutual resource holding, in LiveLock processes are active and responsive, but their actions interfere with each other.

Example: two people trying to pass each other in a narrow corridor, both constantly yielding to each other, but no one passes.

In programming, this can manifest if threads repeatedly try to acquire resources, releasing and acquiring them, but do not make progress.
