The edges in the graph are represented by a given 2D integer array `edges`, where `edges[i] = [ui, vi]` denotes an edge between vertex `ui` and vertex `vi`. Every vertex pair is connected by at most one edge, and no vertex has an edge to itself. Return _the length of the **shortest **cycle in the graph_. If no cycle exists, return `-1`. A cycle is a path that starts and ends at the same node, and each edge in the path is used only once. **Example 1:** ``` **Input:** n = 7, edges = [[0,1],[1,2],[2,0],[3,4],[4,5],[5,6],[6,3]] **Output:** 3 **Explanation:** The cycle with the smallest length is : 0 -> 1 -> 2 -> 0 ``` **Example 2:** ``` **Input:** n = 4, edges = [[0,1],[0,2]] **Output:** -1 **Explanation:** There are no cycles in this graph. ``` **Constraints:** `2 <= n <= 1000` `1 <= edges.length <= 1000` `edges[i].length == 2` `0 <= ui, vi < n` `ui != vi` There are no repeated edges.", + "public_test_cases": [ + {
