How should i handle input for this?

#1

I have understood the approach for solving this but confused for how to take input and solve.Should i take input in form of matrix?

#2

no just take two variables x and y
and add in adjancy list
like this
adjlist[x].push_back(y);
or call addAdjlist(x,y) fun

#3

If i want to do with array there must be some way right? like 2d array or something

#4

This is ques of graph so just got oconfused Can i take normal 2 arrays or there should be matrix or what

#5

make vector of vectors
vector<vector< int>>adjList;
now
cin>>x>>y;
adjList[x].push_back(y);

this is same as 2D array

#6
