Description

Suppose an $n \times n$ array $a$ is used to represent the adjacency matrix of a directed graph:
(1) Write a function to determine the out-degree of a vertex.
(2) Write a function to determine the in-degree of a vertex.
(3) Write a function to determine the number of edges in the graph.

Input Format

The first line: total number of nodes $n$, specified node $m$, nodes are numbered starting from $1$.
The next $n$ lines: the adjacency matrix of the directed graph.
$1\leq n, m, a[i][j]\leq 1000$

Output Format

The first line outputs three numbers: node number $m$, the out-degree of $m$, and the in-degree of $m$ (separated by spaces).
The second line outputs: the total number of edges in the graph.
