Solution in C++ (GCC 9.2.1) (judge verdict: Accepted)

#include<bits/stdc++.h>

using namespace std;

int main () {

    string a;
    cin >> a;

    if(a == "A" ||  a == "B" || a == "C" || a == "D" || a == "E" || a == "F" || a == "G" || a == "H" || a == "I" || a == "J" || a == "K" || a == "L" || a == "M" || a == "N" || a == "O" || a == "P" || a == "Q" || a == "R" || a == "S" || a == "T" || a == "U" || a == "V" || a == "W" || a == "X" || a == "Y" || a == "Z") {
        cout << "A" << endl;
    } else {
        cout << "a" << endl;
    }

    return 0;
