用的是分支结构解题

#include<bits/stdc++.h> using namespace std; int a1,b1,c1,a2,b2,c2; int main(){ cin>>a1>>b1>>c1>>a2>>b2>>c2; if(a1>a2)cout<<"No"; else if(a1<a2)cout<<"Yes"; else{ if(b1>b2)cout<<"No"; else if(b1<b2)cout<<"Yes"; else{ if(c1>c2)cout<<"No"; else if(c1<c2)cout<<"Yes"; else{ cout<<"No"; } } } return 0; }

#include<iostream> using namespace std; int main (){ int a,b,c; int x,y,z; cin>>a>>b>>c>>x>>y>>z; if (a<x || ax&&b<y || ax&&b==y&&c<z){ cout<<"Yes"; }else{ cout<<"No"; } }
