Example: Given linked list: 1->2->3->4->5, and n = 2. After removing the second node from the end, the linked list becomes1->2->3->5. Note: Given n will always be valid. Ans: /** * Definition for singly-linked list. * function ListNode(val) { * this.val = val; * th...
2.The source node has a cost of 0 and all other node has cost of infinity. 3.While there is an unvisited node in the graph do pick the node with the smallest cost, mark it as visited. update all its unvisited neighbor if the cost of that neighbor is less than the cost of the ...

The word can be constructed from letters of sequentially adjacent cells, where adjacent cells are horizontally or vertically neighboring. The same letter cell may not be used more than once. Source ReorderList Kotlin • questions You are given the head of a singly linked-list. The list can...
How do you determine if your singly-linked list has a cycle? In 1980, Brent invented an algorithm that not only worked in linear time, but required less stepping than Floyd's Tortoise and the Hare algorithm (however it is slightly more complex). Although stepping through a 'regular' linked...
❓: Given the head of a singly linked list, reverse the list, & return the reversed list. 🐣: 1️⃣ Input: head = [1,2,3,4,5] Output: [5,4,3,2,1] 2️⃣ Input: head = [1,2] Output: [2,1] 3️⃣ Input: head = [] Output: [] 🐢 Solution: 🔨 Brute...
At the enrolment stage, a database with demographic information is efficiently created which is an array of bins and each bin is a singly linked list. At the de-duplication stage, name strings are reduced and all neighbouring bins of the reduced name strings are used to determine the top k...
