A Thickest Burger HDU - 5948

大的数*2+小的数

#include <bits/stdc++.h>
using namespace std;
#define ll long long
#define INF 0x3f3f3f3f
int main(){int t;cin>>t;while(t--){int a,b;cin>>a>>b;if(a>b)cout<<a*2+b<<endl;else cout<<b*2+a<<endl;}return 0;
}

B-Relative atomic mass HDU - 5949

H是1，O是16，C是12，给你一个字符串，求总值

#include <bits/stdc++.h>
using namespace std;
#define ll long long
#define INF 0x3f3f3f3f
int main(){int t;cin>>t;while(t--){string a;cin>>a;int sum=0;for(int i=0;i<a.length();i++){if(a[i]=='H')sum++;else if(a[i]=='O')sum+=16;else if(a[i]=='C')sum+=12;}cout<<sum<<endl;}return 0;
}
