LeetCode 2807: Insert Greatest Common Divisors in Linked List | Step-by-Step Explanation

Problem Link:leetcode.com/p...
👋 Hey everyone! In this video, we solve LeetCode Problem 2807: Insert Greatest Common Divisors in Linked List. 🚀 I walk you through the problem step-by-step and explain how to calculate the GCD between adjacent nodes in a linked list, and how to insert new nodes containing these GCD values.
🔗 Problem Description: We are given the head of a linked list where each node contains an integer. Between every pair of adjacent nodes, we need to insert a new node with the value equal to the greatest common divisor (GCD) of the two nodes.
💡 Example 1:
Input: [18,6,10,3]
Output: [18,6,6,2,10,1,3]
Explanation:
Insert GCD(18, 6) = 6 between nodes 18 and 6
Insert GCD(6, 10) = 2 between nodes 6 and 10
Insert GCD(10, 3) = 1 between nodes 10 and 3
💡 Example 2:
Input: [7]
Output: [7]
Explanation: No adjacent nodes, so no insertions are needed.
