In the Create Maximum Number problem, we have given two arrays of length n and m with digits 0-9 representing two numbers. Create the maximum number of length k <= m + n from the digits of the two. The relative order of the digits from the same array must …
Problem Description of Queue Reconstruction by Height Suppose you have a random list of people standing in a queue. Each person is described by a pair of integers (h, k), where h is the height of the person and k is the number of people in front of this person …
Last Stone Weight is a problem in which we have a set of stones having some positive weights. Now we perform a task on it till we left 1 stone or no stone. We always pick two stones having the highest weight_value and smash them together. Let’s suppose the weight …
Rotate array is a problem in which we have given an array of size N. We have to rotate the array in the right direction. Each element shift by one position right and last element of the array come to the first position. So, we have given a value K …
Dijkstra is the shortest path algorithm. Dijkstra algorithm is used to find the shortest distance of all nodes from the given start node. It logically creates the shortest path tree from a single source node, by keep adding the nodes greedily such that at every point each node in the …
Problem Statement In the “Stock Buy Sell to Maximize Profit” problem we have given an array that contains stock price on each day, find the maximum profit that you can make by buying and selling in those days. Here, we can buy and sell multiple times but only after selling …
Problem Statement In the maximum length of chain pairs problem we have given n pairs of numbers, find the longest chain in which (c, d) can follow (a, b) if b < c. In the given pairs the first element is always smaller than the second. Example Input [{12, 14}, …
