Tree traversals are methods used to visit each node in a tree data structure.

• Inorder traversal: Visit left subtree, then root, then right subtree. Example: 1. Left -> Root -> Right

• Preorder traversal: Visit root, then left subtree, then right subtree. Example: 1. Root -> Left -> Right

• Postorder traversal: Visit left subtree, then right subtree, then root. Example: 1. Left -> Right -> Root

The answer describes how to check if a linked list is a palindrome or not.

• Traverse the linked list and store the values in an array

• Compare the elements of the array from both ends to check for palindrome

• Alternatively, use two pointers to traverse the linked list, one slow and one fast, and reverse the first half of the list while traversing

To find the Kth element from the end of a linked list, we can use the two-pointer approach.

• Initialize two pointers, 'fast' and 'slow', pointing to the head of the linked list.

• Move the 'fast' pointer K steps ahead.

• Move both 'fast' and 'slow' pointers one step at a time until 'fast' reaches the end of the linked list.

• The 'slow' pointer will be pointing to the Kth element from the end.

To check if a linked list has a loop, we can use the Floyd's cycle-finding algorithm.

• Use two pointers, one moving at twice the speed of the other

• If there is a loop, the fast pointer will eventually catch up with the slow pointer

• If the fast pointer reaches the end of the list, there is no loop

The Lowest Common Ancestor (LCA) of a binary tree can be found in place using a recursive approach.

• Start from the root node and recursively check if both nodes are present in the left and right subtrees.

• If one node is found in the left subtree and the other in the right subtree, then the current node is the LCA.

• If both nodes are found in the left subtree, recursively search for the LCA in the left subtree.

• If both nodes are found in the right subtree, recursively search for th...read more

Knapsack and coin change problems are classic dynamic programming problems.
