Answer 1

#include <iostream>

using namespace std;

   
int get_last_character_repeated(string s) { 
    int len = s.length(), ch_idx = -1;
     
    for (int i = 0; i < len; i++) { 
        for (int j = i + 1; j < len; j++) { 
            if (s[i] == s[j]) { 
                ch_idx = i;
                break;
            } 
        }
    } 
    return ch_idx; 
}   

int main() {
    string s = "abcdxypcbadom"; 
    int i = get_last_character_repeated(s); 
     
    if (i == -1) 
        cout << "Not found"; 
    else
        cout << s[i]; 
}
