title: Sum input integer by itself, integer times
body: <p>Salam, I'm given a user input that I have to sum it by itself n-times. Which means if the input is &quot;5&quot; for example, I should return <code>5 + 5 + 5 + 5 + 5 = 25</code><br />
  I used:</p>
  <pre><code>def sum(user_input):
      inp_sum = 0
      string = ''
      for n in range(0, user_input, 1):
          inp_sum += user_input
          if n != user_input -1:
              string+= &quot;5 + &quot;
          else: string += '5'
      return string + ' = ' + str(inp_sum)
  </code></pre>
  <p>but it returns</p>
  <pre><code>Failed for value=6 
  Expected: 6 + 6 + 6 + 6 + 6 + 6 = 36
  Actual: 5 + 5 + 5 + 5 + 5 + 5 = 36
  </code></pre>
  <p>what is the solution?</p>
