Merge K Sorted Arrays

#1

I have got Segmentation Fault.

#2

First resize vector to that size. Before taking input.

#3

vector<vector<int>>v(m,vector<int>(n));

like this?

#4

Yes, like this, else it will be of size 0.

#5

I did that. But now Iā€™m getting output like:
0 0 0 0 0 0 0 0 0 0 0 0 0 1 2 3 4 5 6 7 8 9 10 11
But output should be like:

0 1 2 3 4 5 6 7 8 9 10 11

#6

Yes, that is becuase, you are using push_back(), which appends after the already resized array.

If you want to use push_back(), resize it as,

vector<vector<int>>v(m)

else, just use,

cin >> v[i][j];
