An Euler tour of a directed graph  with n vertices and m edges is a cycle that traverses each edge of   exactly once according to its direction. Such a tour always exists if   is connected and the in-degree equals the out-degree of each vertex in   . Describe an O(n + m)-time algorithm for finding an Euler tour of such a directed graph
