Eulerian Path is a path in a graph that visits every edge exactly once. Eulerian Circuit is an Eulerian Path that starts and ends on the same vertex. Given the number of vertices v and adjacency list adj denoting the graph. Find that there exists the Euler circuit or not. Return 1 if there exist alteast one eulerian path else 0.

Note that: Given graph is connected.

Example 1:

Input:
v = 4
edges[] = {{0, 1},
{0, 2},
{1, 3},
{2, 3}}

Output:
1
Explanation: corresponding adjacency list will be {{1, 2},{0, 3},{0, 3},{1, 2}}
One of the Eularian circuit
starting from vertex 0 is as follows:
0-1-3-2-0
Example 2:

Input:
v = 3
edges[] = {{0, 1},
{0, 2}}


Output:
0
Explanation: corresponding adjacency list will be {{1, 2}}
No Eulerian path is found
