SDE - 1

You are given a graph with 'N' vertices numbered from '1' to 'N' and 'M' edges. You have to colour this graph in two different colours, say blue and red such that no two vertices connected by an edge are of the same colour.

Note :

The given graph may have connected components.

For a given array with N elements, you need to find the length of the longest subsequence from the array such that all the elements of the subsequence are sorted in strictly increasing order.

Strictly Increasing Sequence is when each term in the sequence is larger than the preceding term.

For example:

[1, 2, 3, 4] is a strictly increasing array, while [2, 1, 4, 3] is not.

Given two singly linked lists, 'FIRST_HEAD' and 'SECOND_HEAD'. Your task is to find the 'MERGING POINT' i.e. the data of the node at which merging starts. If there is no merging, return -1.

For example:-

The given Linked Lists are merging at node c1.
In this case, c1 is 'MERGING POINT'.

Given an undirected and disconnected graph G(V, E), containing 'V' vertices and 'E' edges, the information about edges is given using 'GRAPH' matrix, where i-th edge is between GRAPH[i][0] and GRAPH[i][1]. print its DFS traversal.

V is the number of vertices present in graph G and vertices are numbered from 0 to V-1. 

E is the number of edges present in graph G.

Note :

The Graph may not be connected i.e there may exist multiple components in a graph.
