using namespace std;
int main() {
// Declare and accept input for string variable passCode
string passCode;
cin >> passCode;
// declaring character array
char ch[2];
// copying the contents of the string to char array
strcpy(ch, passCode.c_str());
// Iterate char arrray ch
for(int i=0; i<2;i++)
{
// Check if first and second element is an alphabet
if((ch[i]>='a' && ch[i]<='z') || (ch[i]>='A' && ch[i]<='Z'))
{
// Replace if the condition above is true
ch[i] = '_';
}
}
// Print passCode
for (int i = 0; i < n; i++)
cout << ch[i];
return 0;
}
