Ans. 
Detect if a singly linked list forms a cycle by checking if a node's next points back to a previous node.
• Use Floyd's Cycle Detection Algorithm to determine if there is a cycle in the linked list.

• Maintain two pointers, one moving at double the speed of the other, if they meet at any point, there is a cycle.

• If one of the pointers reaches the end of the list (null), there is no cycle.

Ans. 
ZigZag tree traversal is a method to traverse a binary tree in a zigzag pattern.
