#include <bits/stdc++.h>
#define rep(i,n) for (int i=0; i< int (n); i++)
using namespace std;
typedef long long ll;

int main(){
char x;
cin >> x;
if(x=='A'||x=='B'||x=='C'||x=='D'||x=='E'||x=='F'||x=='G'||x=='H'||x=='I'||x=='J'||x=='K'||x=='L'||x=='M'||x=='N'||x=='O'||x=='P'||x=='Q'||x=='R'||x=='S'||x=='T'||x=='U'||x=='V'||x=='W'||x=='X'||x=='Y'||x=='Z') cout << "A" << endl;
else cout << "a" << endl;
