作业2.7_2
麻麻我更委屈了!!!
天平(即风铃)AC代码:两个答案之间空行隔开也就罢了,为嘛最后一行还不能多空行?!
#include<cstdio>
using namespace std;
bool solve(int &w){
int w1,d1,w2,d2;
bool b1=1,b2=1;
scanf("%d%d%d%d",&w1,&d1,&w2,&d2);
if(w1==0)b1=solve(w1);
if(w2==0)b2=solve(w2);
w=w1+w2;//F=G1+G2;
return b1&&b2&&(w1*d1==w2*d2);
}
int main(){
int t,w;
scanf("%d",&t);
while(t--)
{
if(solve(w))printf("YES\n");
else printf("NO\n");
if(t)printf("\n");
}
return 0;
}
反片语代码:
#include<bits/stdc++.h>
using namespace std;
map<string,int> cnt;
vector<string>word,ans1;
string s;
string change(string s)
{
string t=s;
for(int i=0;i<t.size();i++)
{
t[i]=tolower(t[i]);
}
sort(t.begin(),t.end());
return t;
}
int main()
{
while(cin>>s)
{
if(s[0]=='#')break;
word.push_back(s);
string ans=change(s);
if(!cnt.count(ans)) cnt[ans]=0;
cnt[ans]++;
}
for(int i=0;i<word.size();i++)
if(cnt[change(word[i])]==1)ans1.push_back(word[i]);
sort(ans1.begin(),ans1.end());
for(int i=0;i<ans1.size();i++) cout<<ans1[i]<<endl;
return 0;
}
