You are given a mysterious language (codenamed "Secret") available in "Custom Test" tab. Find out what this language is and write a program which outputs its name. Note that the program must be written in this language.

Input

This program has only one test, and it's empty (it doesn't give your program anything to read).

Output

Output the name of the mysterious language.

Examples
#include <bits/stdc++.h>
using namespace std;
const long long MAXN = 4e6;
const long long mod = 1e6 + 3;
long long log_10(long long n) {
  long long cnt = 0;
  while (n >= 10) {
    n /= 10;
    cnt++;
  }
  return cnt;
}
void NO_Exit() {
  cout << "NO" << endl;
  exit(0);
}
void NO() { cout << "NO" << endl; }
void YES_Exit() {
  cout << "YES" << endl;
  exit(0);
}
void YES() { cout << "YES" << endl; }
void coiarr(long long a[], long long n) {
  if (n == 0) return;
  cout << a[0];
  for (long long i = 1; i < n; i++) cout << " " << a[i];
}
void cosarr(string a[], long long n) {
  if (n == 0) return;
  cout << a[0];
  for (long long i = 1; i < n; i++) cout << " " << a[i];
}
void ciiarr(long long a[], long long n) {
  for (long long i = 0; i < n; i++) cin >> a[i];
}
void cisarr(string a[], long long n) {
  for (long long i = 0; i < n; i++) cin >> a[i];
}
void fill_bool(bool a[], long long n, bool flag) {
  for (long long i = 0; i < n; i++) a[i] = flag;
}
int main() {
  ios_base::sync_with_stdio(false), cin.tie(0), cout.tie(0);
  cout << "INTERCAL";
  return 0;
}
