What is deadlock condition in multi threading and how to prevent it?

Question

Accepted Answer

Deadlock in multithreading occurs when two or more threads are waiting for each other to release resources, causing them to be stuck indefinitely.

Deadlock can be prevented by using proper synchronization techniques like avoiding nested locks, using timeouts, and implementing a deadlock detection algorithm.
One common example of deadlock is the dining philosophers problem, where multiple philosophers are sitting at a table with chopsticks and can only eat if they have both chopsticks, leading to potential deadlocks if they all pick up one chopstick and wait for the other.
Another example is when two threads are trying to access two resources in opposite order, causing each thread to wait for the other to release the resource they need.
