//之前一直尝试用vector存储path,但是每次错误后回退上一级节点时不能争取回退,导致探索路径正确,但是输出不正确,用参数num,标记前一个路径点的位置传递参数,就好多了 //其中在输入时就将后继节点按照权值大小排列,是可以学习方法,再输入时就处理好,方便dfs探索,有几道PAT题目都是在该基础上对路径加要求,都可以直接改进输出那一部分代码,更新更和要求的路径,全部遍历完,就可得到所求符合要求的的路径 //参数传递的思想也不错,之前不习惯,总是直接把ans存进vector,最后输出 #in…

1053 Path of Equal Weight 给定一个非空的树,树根为 RR. 树中每个节点 TiTi 的权重为 WiWi. 从 RR 到 LL 的路径权重定义为从根节点 RR 到任何叶节点 LL 的路径中包含的所有节点的权重之和. 现在给定一个加权树以及一个给定权重数字,请你找出树中所有的权重等于该数字的路径(必须从根节点到叶节点). 例如,我们考虑下图的树,对于每个节点,上方的数字是节点 ID,它是两位数字,而下方的数字是该节点的权重. 假设给定数为 2424,则存在 44 个具有相同…
