  我的解法: 建树,递归判断 #include<cstdio> #include<cstring> #include<iostream> #include<string> #include<algorithm> using namespace std; struct Node { Node() { wl=wr=dl=dr=; l=r=; } int wl; int dl; int wr; int dr; Node* l; Node* r; };…
UVa 839 Not so Mobile(树的递归输入) 判断一个树状天平是否平衡,每个测试样例每行4个数 wl,dl,wr,dr,当wl*dl=wr*dr时,视为这个天平平衡,当wl或wr等于0是,下一行将是一个子天平,如果子天平平衡,wl为子天平的wl+wr ,否则整个天平不平衡 #include<iostream> using namespace std; bool solve(int &w) { int wl,dl,wr,dr; cin>>wl>>dl…
