c++和Python解法如下

c++解法

#include <bits/stdc++.h>
using namespace std;
int main(){
    int n;
    cin >> n;
    for (int i = 0; i <= n; i++){
        if(i % 3 == 2 && i % 5 == 3 && i % 7 == 2){
            cout << i << endl;            
        }
    }
    return 0;
}

Python解法

a = int(input())
for i in range (a):
    if i % 3 == 2 and i % 5 == 3 and i % 7 == 2:
        print(i)
