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 of integers where 1 ≤ a[i] ≤ n (n = size of array), some elements appear twice and others appear once. Find all the elements of [1, n] inclusive that do not appear in this array. Could you do it without extra space and in O(n) runtime? You may assume the...
C/C++ Coding Exercise - Find the Duplicate Number Since the input numbers are within the range of 1 to n inclusive, if we pick a number and count how many numbers are smaller than it, if it is bigger than the number, meaning there is a duplicate below it
