  • In Dijkstra's algorithm, each node maintains a backpointer to the previous node in the shortest path from the source.(在Dijkstra算法中,每个节点都维护一个回指针,指向从源节点到当前节点最短路径中的前一个节点。)
  • The backpointer in a linked list can be used to traverse the list in reverse order.(链表中的回指针可用于反向遍历链表。)
  • When implementing a graph traversal algorithm, backpointers help in reconstructing the path from the target node back to the start node.(在实现图遍历算法时,回指针有助于从目标节点回溯重建路径到起始节点。)
  • In dynamic programming, a backpointer can store the optimal substructure's predecessor to reconstruct the solution.(在动态规划中,回指针可以存储最优子结构的前驱,以重建解决方案。)
  • The backpointer of a node in a tree structure points to its parent node, facilitating upward traversal.(树结构中节点的回指针指向其父节点,便于向上遍历。)
