WebFeb 4, 2024 · Complexity Analysis: Time Complexity: O (N*logV) where V is the weight of a node in the tree. In bfs, every node of the tree is processed once and hence the complexity due to the bfs is O (N) if there are total N nodes in the tree. Also, while processing every node, in order to check if the node values are co-prime or not, the inbuilt __gcd (A ...
