Description ​ 给出一个数组a,要求构造一颗树,使节点x距离最远的点的距离为\(a_x\). Input ​ 第一行一个正整数NN(2≤N≤1002≤N≤100) ​ 接下来一行,有NN个正整数,描述序列a1,a2,...,aNa1,a2,...,aN(1≤ai≤N−11≤ai≤N−1) Output ​ 如果对于输入的序列存在这样的树,则输出"Possible",否则输出"Impossible".二者皆不含引号. Sample Input #Sampl…
Tree Restoring Time limit : 2sec / Memory limit : 256MB Score : 700 points Problem Statement Aoki loves numerical sequences and trees. One day, Takahashi gave him an integer sequence of length N, a1,a2,…,aN, which made him want to construct a tree. A…
Binary Tree Restoring 思路: 递归 比较a序列和b序列中表示同一个子树的一段区间,不断递归 代码: #include<bits/stdc++.h> using namespace std; #define LL long long #define pb push_back #define mem(a,b) memset(a,b,sizeof(a)) ; int a[N],b[N],par[N],posa[N],posb[N],sum[N],n; void dfs(int…
Binary Tree Restoring Time Limit: 1 Second      Memory Limit: 65536 KB      Special Judge Given two depth-first-search (DFS) sequences of a binary tree, can you find a binary tree which satisfies both of the DFS sequences? Recall that a binary tree i…
Jquery LigerUI Tree是Jquery LigerUI()的插件之一,使用它可以快速的构建树形菜单.呵呵 废话不说了,直入正题,下面介绍C#结合ligerui 构造树形菜单的两种方法 1.ID/PID格式 JqueryLigerUI官网上的例子是这样的: 复制代码  1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DT…

Problem Statement Aoki loves numerical sequences and trees. One day, Takahashi gave him an integer sequence of length N, a1,a2,…,aN, which made him want to construct a tree. Aoki wants to construct a tree with N vertices numbered 1 through N, such th…
ACM思维题训练集合 You are given two integers n and d. You need to construct a rooted binary tree consisting of n vertices with a root at the vertex 1 and the sum of depths of all vertices equals to d. A tree is a connected graph without cycles. A rooted tre…
