Redundant Connection

Understand how to apply the union find algorithm to detect and remove the redundant edge in an undirected graph, making it a tree with no cycles. Learn to interpret graph structures and implement solutions to connected graph problems with one cycle.

We'll cover the following...

Statement

We’re given an undirected graph consisting of nn nodes. The graph is represented as an array called edges, of length nn, where edges[i] = [a, b] indicates that there is an edge between nodes a and b in the graph.

Return an edge that can be removed to make the graph a treeA tree is an undirected graph that is connected and has no cycles. of nn ...
