If the two linked lists have no intersection at all, return null. The linked lists must retain their original structure after the function returns. You may assume there are no cycles anywhere in the entire linked structure. Your code should preferably run in O(n) time and use only O(1) ...

Given an array nums containing n + 1 integers where each integer is between 1 and n (inclusive), prove that at least one duplicate number must exist. Assume that there is only one duplicate number, find the duplicate one. Submit your solution:https://leetcode.com/problems/find-the-duplicat...
Using two pointers, you can traverse both arrays without actually merging them, thus without the extra space. Both pointers are initialized to point to head of A and B respectively, and the pointer that has the larger finding intersection of two sorted arrays. The best solution, but non-...
