In this post-lab you will demonstrate your understanding of while loops by writing a function that uses a while loop to solve a mathematical problem.
Details
  Create a function called summation_less_than(max_sum)
  in a filed called summation.py.  This function should
  return the largest number of sequential integers that sum to less
  than the specified positive integer max_sum.  Put
  another way, return the \(n\) such that:
$$(\sum_{i=0}^n i) < max\_sum$$
Make sure you have sufficient test cases and that you follow all of the course's coding conventions.
Sample Test Cases
| Function Parameters | Expected Output | 
|---|---|
| 5 | 2 | 
| 6 | 2 | 
| 7 | 3 | 
Submission
Submit your program as a .py file on the course Inquire page before class on Monday October 6th.
