GetMxOutDegNId
'''''''''''

.. function:: GetMxOutDegNId(Graph)

Returns a randomly chosen node from all the nodes with the maximum degree.

Parameters:

- *Graph*: graph (input)
    A Snap.py graph or a network

Return value:

- *NId*: int (output)
    Id of a node with maximum out degree

The following example shows how to use GetMxOutDegNId with
:class:`PNGraph`, :class:`PUNGraph`, and :class:`PNEANet`::

    import snap

    G1 = snap.PNGraph.New()
    G1.AddNode(1)
    G1.AddNode(2)
    G1.AddNode(3)
    G1.AddEdge(1,2)
    G1.AddEdge(2,1)
    G1.AddEdge(1,3)
    G1.AddEdge(1,1)
    G1.AddEdge(2,3)
    nid = snap.GetMxOutDegNId(G1) # nid == 1

    G2 = snap.PUNGraph.New()
    G2.AddNode(1)
    G2.AddNode(2)
    G2.AddNode(3)
    G2.AddNode(4)
    G2.AddEdge(1,2)
    G2.AddEdge(1,3)
    G2.AddEdge(1,4)
    G2.AddEdge(2,4)
    nid = snap.GetMxOutDegNId(G2) # nid == 1

    G3 = snap.PNEANet.New()
    G3.AddNode(1)
    G3.AddNode(2)
    G3.AddNode(3)
    G3.AddEdge(1,2)
    G3.AddEdge(2,1)
    G3.AddEdge(1,3)
    G3.AddEdge(1,1)
    G3.AddEdge(2,3)
    nid = snap.GetMxOutDegNId(G3) # nid == 1
