To lock a file in Linux, use the flock command or the fcntl system call.
The flock command can be used to lock a file by acquiring an exclusive or shared lock.
The fcntl system call can be used to lock a file by setting the F_SETLK or F_SETLKW command.
Locking a file prevents other processes from modifying or accessing it until the lock is released.
Locking can be done at the file level or at specific regions within a file...

To find a loop in a linked list, we can use the Floyd's cycle-finding algorithm.
Use two pointers, one moving at a speed of one node at a time and the other at a speed of two nodes at a time.
If there is a loop, the two pointers will eventually meet at the same node.
To find the starting point of the loop, move one pointer back to the head and then move both pointers at a speed of one node at a time.
The point where they m...
