How do you print all elements of a linked list.
Given two unsorted arrays, one with event start times and one with end times, find out if any two events overlap.
Given an array where each entry can be another array, and so forth, flatten the array. [4, [3, 6, [9, 1, 9, [5, 1]]], 8] -> [4, 3, 6, 9, 1, 9, 5, 1, 8]
Return the head node of the singly linked list with each pair of nodes swapped. If there is a last odd node leave it in place. Example: Input: 1 -> 2 -> 3 -> 4 -> 5 Output: 2 -> 1 -> 4 -> 3 -> 5
You are given a list of strings (e.g. ["cat", "dog", "hat", "apple", "c"] ).
