Code : Is Connected ?

  Given an undirected graph G(V,E), check if the graph G is connected graph or not. Note: 1. V is the number of vertices present in graph G and vertices are numbered from 0 to V-1. 2. E is the number of edges present in graph G. Input Format : The first line of input contains two integers, that denote the value of V and E. Each of the following E lines contains two integers, that denote that there exists an edge between vertex a and b. Output Format : The first and only line of output contains "true" if the given graph is connected or "false", otherwise. Constraints : 0 <= V <= 1000 0 <= E <= (V * (V - 1)) / 2 0 <= a <= V - 1 0 <= b <= V - 1 Time Limit: 1 second Sample Input 1: 4 4 0 1 0 3 1 2 2 3 Sample Output 1: true Sample Input 2: 4 3 0 1 1 3 0 3 Sample Output 2: false Sample Output 2 Explanation The graph is not connected, even though vertices 0,1 and 3 are connected to each other but there isn’t any path from vertices 0,1,3 to vertex...

Coding Ninjas

  Given a NxM matrix containing Uppercase English Alphabets only. Your task is to tell if there is a path in the given matrix which makes the sentence “CODINGNINJA” . There is a path from any cell to all its neighbouring cells. For a particular cell, neighbouring cells are those cells that share an edge or a corner with the cell. Input Format : The first line of input contains two space separated integers N and M, where N is number of rows and M is the number of columns in the matrix. Each of the following N lines contain M characters. Please note that characters are not space separated. Output Format : Print 1 if there is a path which makes the sentence “CODINGNINJA” else print 0. Constraints : 1 <= N <= 1000 1 <= M <= 1000 Time Limit: 1 second Sample Input 1: 2 11 CXDXNXNXNXA XOXIXGXIXJX Sample Output 1: 1 bool hasPath ( vector < vector < char >> & board , int n , int m ) { // Write your code here. } #include < iostream > #include ...
