Given an integer array arr
of size 'N' containing only 0s, 1s, and 2s, write an algorithm to sort the array.
The first line contains an integer 'T' representing the n...
Sort an array of 0s, 1s, and 2s in linear time complexity.
Use three pointers to keep track of 0s, 1s, and 2s while traversing the array.
Swap elements based on the values encountered to sort the array in-place.

You are provided with the head of a linked list containing integers. Your task is to determine if the linked list is circular.
Detect if a given linked list is circular by checking if it forms a closed loop.
Traverse the linked list using two pointers, one moving at double the speed of the other.
If the two pointers meet at any point, the linked list is circular.
If the faster pointer reaches the end of the list (NULL), the linked list is not circular.
