Now, we would like to merge these accounts. You signed in with another tab or window. to refresh your session. You signed out in another tab or window. Given an integer matrix, find the length of the longest increasing path. Reload to refresh your session. You may NOT move diagonally or move outside of the boundary (i.e. Given a binary search tree (BST) with duplicates, find all themode(s)(the most frequently occurred element) in the given BST.. Given a list accounts, each element accounts[i] is a list of strings, where the first element accounts[i][0] is a name, and the rest of the elements are emails representing emails of the account. Reload to refresh your session. Two accounts definitely belong to the same person if there is some email that is common to both accounts. wrap-around is not allowed). Largest Component Size by Common Factor Question: Given a non-empty array of unique positive integers A, consider the following graph: There are A.length nodes, labelled A[0] to A[A.length - 1]; Assume a BST is defined as follows: The left subtree of a node contains only nodes with keys less than or equal to the node's key. Approach: The idea is to use a variable count to store the number of connected components and do the following steps: Initialize all vertices as unvisited. For all the vertices check if a vertex has not been visited, then perform DFS on that vertex and increment the variable count by 1.; Below is the implementation of the above approach: You signed out in another tab or window. You signed in with another tab or window. Given n nodes labeled from 0 to n - 1 and a list of undirected edges (each edge is a pair of nodes), write a function to find the number of connected components in an undirected graph. Tarjan’s Algorithm to find Strongly Connected Components Finding connected components for an undirected graph is an easier task. From each cell, you can either move to four directions: left, right, up or down.
