# Create a function/method/routine called <code>one_of_n</code> that given <code>n</code>, the number of actual lines in a file, follows the algorithm above to return an integer - the line number of the line chosen from the file. <br>The number returned can vary, randomly, in each run.

# Use <code>one_of_n</code> in a ''simulation'' to find what woud be the chosen line of a 10 line file simulated 1,000,000 times.
# Use <code>one_of_n</code> in a ''simulation'' to find what would be the chosen line of a 10-line file simulated 1,000,000 times.
# Print and show how many times each of the 10 lines is chosen as a rough measure of how well the algorithm works.
