You will be given a row of numbers (x), and a single number (n). Your job is to write a script that will stretch out the row of numbers, putting n numbers between each of the numbers in x. The numbers you put in x will be linearly interpolated.

For example, if x=[1 5 2 4 3] and n=1, your output should be:

y=[1 3 5 3.5 2 3 4 3.5 3]

There is n=1 number between all of the original values of x, and the new values are linearly interpolated from the original values of x:

• 1 --> 3 --> 5
• 5 --> 3.5 --> 2
• 2 --> 3 --> 4
• 4 --> 3.5 --> 3
