Determine if a given singly linked list of integers forms a cycle or not.
A cycle in a linked list occurs when a node's next
points back to a previous node in the ...
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.
Given a list of integers of size N
, your task is to determine the Next Greater Element (NGE) for every element. The Next Greater Element for an element X
is the firs...
Find the Next Greater Element for each element in a list of integers.
Iterate through the list of integers from right to left.
Use a stack to keep track of elements for which the Next Greater Element is not yet found.
Pop elements from the stack until a greater element is found or the stack is empty.
Assign the Next Greater Element as the top element of the stack or -1 if the stack is empty.

Find first missing positive number in an array in O(n) time and O(1) space.
Traverse the array and mark the presence of each positive integer by changing the sign of the corresponding index.
Traverse the array again and return the index of the first positive integer.
If all integers are present, return the length of the array + 1.
Example: [3, 4, -1, 1] => mark 3rd and 4th index as negative => return 2.
Example: [1, 2, 0] =...

Kadane's Algorithm, Even Numbers at even index & odd at odd index, print out the second highest node of the tree
ZigZag tree traversal is a method to traverse a binary tree in a zigzag pattern.
In ZigZag tree traversal, we visit the nodes of a binary tree in a zigzag pattern, moving from left to right and then right to left.
We can use a stack or a queue to implement ZigZag tree traversal.
The algorithm involves maintaining two stacks or two queues to keep track of the nodes at each level.
We start with the root node and alternate be...
