此题ACGO最长代码

自己看

#include<bits/stdc++.h>
using namespace std;
int main(){
	int n;
	cin >> n;
    for(int i = 1;i <= n;i++){
        int a = 0,b0 = 0,c00 = 0,d000 = 0,e0000 = 0;
        if(i < 10){
            cout << i << endl;
        }else if(i >= 10 && i < 100){
            a = i % 10;
            b0 = i / 10;
            if(a * 10 + b0 == i){
                cout << i << endl;
            }
        }else if(i >= 100 && i < 1000){
            a = i % 10;
            b0 = i % 100 / 10;
            c00 = i / 100;
            if(a * 100 + b0 * 10 + c00 == i){
                cout << i << endl;
            }
        }else if(i >= 1000 && i < 10000){
            a = i % 10;
            b0 = i % 100 / 10;
            c00 = i % 1000 / 100;
            d000 = i / 1000;
            if(a * 1000 + b0 * 100 + c00 * 10 + d000 == i){
                cout << i << endl;
            }
        }else if(i >= 10000 && i < 100000){
            a = i % 10;
            b0 = i % 100 / 10;
            c00 = i % 1000 / 100;
            d000 = i % 10000 / 1000;
            e0000 = i / 10000;
            if(a * 10000 + b0 * 1000 + c00 * 100 + d000 * 10 + e0000 == i){
                cout << i << endl;
            }
        }
    }
	return 0;
}

秃然康到有更好的解法！！！


但他就是能AC
啊哈
