一本通1064：思路1.#include <bits/stdc++.h>#define f(i,j,n) for(register int i=j;i<=n;i++)using namespace std;typedef long long ll;inline ll read(){ ll x=0; int f=1; char ch=getchar(); while(!isdigit(ch)) { if(ch=='-') f=-1; ch=getchar(); } while(isdigit(ch)) x=(x<<1)+(x<<3)+ch-48,ch=getchar(); return x*f;}int n=read();ll a=0,b=0,c=0; signed main(){ f(i,1,n) a+=read(),b+=read(),c+=read(); cout<<a<<' '<<b<<' '<<c<<' '<<a+b+c<<endl; return 0;}2.#include<bits/stdc++.h>using namespace std;int main(){ int n; cin>>n; int a[52]; for(int i=0;i<n*3;i++){ cin>>a[i]; } int f=1,j=a[0],y=a[1],t=a[2]; for(int i=3;i<n*3;i++){ if(f==1){ j=j+a[i]; } if(f==2){ y=y+a[i]; } if(f==3){ t=t+a[i]; } if(f==3){ f=0; } f++; } int h; h=j+y+t; cout<<j<<" "<<y<<" "<<t<<" "<<h; return 0;}哪个好？
