title: What does `int` parameter in `map` function of Python 3?
body: <pre><code>if __name__ == '__main__':
  n = int(input())
  arr = map(int, input().split())
  </code></pre>
  
  <p>In the above code, map function taking two parameters, I got the understanding of the second parameter what it does but I am not getting 'int' parameter.</p>
