#include <bits/stdc++.h> using namespace std; int baron(int a){ int b=a,x=0; while(b>0){ x=x*10+b%10; b/=10; } if(x==a){ return true; }else{ return false; } } int main(){ int a; cin>>a; if(baron(a)){ cout<<"Yes"; }else{ cout<<"No"; } }

我不会

千万不要用函数 python代码: python万岁！！！！！！！！！！！！

#include<bits/stdc++.h> #include<cmath> using namespace std; bool huiwen(int n) { int sum=0,t=n; while(t) { int r=t%10; sum = sum*10+r; t/=10; } return sum == n; } int main() { int n; cin>>n; if(huiwen(n)) cout<<"Yes"; else cout<<"No"; return 0; }

#include<iostream> #include<bits/stdc++.h> using namespace std; int hw(int a=0){ int b=0; while(a){ b=b*10+a%10; a/=10; } return b; } int main(){ int a=0; cin>>a; if(hw(a)==a){ cout<<"Yes"<<endl; }else{ cout<<"No"<<endl; } }

点个关注！！！
