# PROBLEM:

The new CodeChef Learn module has two courses for each language.

If there are courses for N languages, how many courses are present in total?

# EXPLANATION:

With two courses for each language, if there are N languages there will be 2\times N courses.

So, the solution is to read in N and print 2\times N.

# TIME COMPLEXITY

\mathcal{O}(1) per test case.

# CODE:

## Code (C++)

```
#include <iostream>
using namespace std;
int main() {
int n;
cin >> n;
cout << 2*n << '\n';
return 0;
}
```

## Code (Python)

```
n = int(input())
print(2 * n)
```
