A and B wants to reach some destination in an undirected graph using the least number of unique edges.↵
Find the count of unique edges.↵
↵
Let's say the two paths come out to be this..↵
A-x-y-D↵
B-y-D↵
↵
Output : 4↵
↵
Explanation :↵
A-x, x-y, y-D and B-y↵
↵
↵
↵
Follow up: What if there are multiple sources?↵
↵
↵
↵
Can someone help me to solve this optimally?↵
