The problem can be found at the following link:
Check for the existence of an Eulerian cycle in the graph.
If every node in the graph has an even degree, it implies the existence of an Eulerian cycle. To determine this, sum the elements in each vector in the input paths
.
If any vector accumulate an odd sum, the function returns false
, indicating the absence of an Eulerian cycle.
To understand the Euler circuit please
Time Complexity : O(N*M)
, where N
is the number of vectors in paths
and M
is the average number of elements in each vector.
Auxiliary Space Complexity : O(1)
, as we are not using any extra space except for some variables.
