Full Stack Engineer Coding medium

Given a grid where each cell can have a 0 (empty), 1 (fresh orange), or 2 (rotten orange), every minute, any fresh orange that is 4-directionally adjacent to a rotten orange becomes rotten. Return the minimum number of minutes that must elapse until no cell has a fresh orange. If this is impossible, return -1.

Find the first non-repeating character in a stream of characters. You need to design a class with an insert(char c) method and a getFirstNonRepeating() method.

#Queue #Hash Map #Doubly Linked List
Full Stack Engineer Coding hard

You are given an array of k linked-lists, each linked-list is sorted in ascending order. Merge all the linked-lists into one sorted linked-list and return it.

#Heap #Divide and Conquer #Linked List

Given a circular integer array nums of length n, return the next greater element for every element in nums. The next greater element of a number x is the first greater number to its traversing-order next in the array.

#Stack #Monotonic Stack #Arrays
Full Stack Engineer Coding medium

There is an integer array nums sorted in ascending order (with distinct values) that is possibly rotated at an unknown pivot index. Given an integer target, return its index if it is in nums, or -1 if it is not in nums. You must write an algorithm with O(log n) runtime complexity.
