Description
Edges are subdivided into nodes. Starting from node 0 with maxMoves, find how many nodes (including subdivided nodes) are reachable.
Examples
Input:
edges = [[0,1,10],[0,2,1],[1,2,2]], maxMoves = 6, n = 3Output:
13Explanation:
13 nodes reachable.
Input:
edges = [[1]], maxMoves = 6, n = 3Output:
1Explanation:
Minimal case with a single-element matrix.
Input:
edges = [[0,1,4],[1,2,3],[2,3,1]], maxMoves = 8, n = 4Output:
11Explanation:
Starting from node 0 with 8 moves: node 1 is reached in 4 moves, node 2 in 7 moves (4+3), and node 3 in 8 moves (7+1). This covers all 4 original nodes plus 7 subdivided nodes along the edges, totaling 11 reachable nodes.
Constraints
- •
0 ≤ edges.length ≤ min(n*(n-1)/2, 10⁴)
