Merge k sorted arrays hidden test cases issue

Hello @samriddhi.srivastava2017,

This happening because you have missed an important constraint given in question:
Elements of array <= |10^15|

Thus, int datatype is not enough to store this big value.
Rather use long long int.

Hope, this would help.
Give a like, if you are satisfied.

Hello @samriddhi.srivastava2017,

Your code is traversing over the arrays column by column, which is failing for the test cases like:
2 4
1 6 7 8
5 2 3 4
Your Output:
1 5 2 6 3 7 4 8
Expected output:
1 2 3 4 5 6 7 8

Flow:
pq={]
pq={5,1}
pop and print 1, push 6: pq={6,5}
pop and print 5, push 2: pq={6,2}
//This is the error.

Hope, this would help.
Give a like, if you are satisfied.
