Flatten the Curve

Given a list of integers, replace every number with the mean of all numbers.

Examples

flatten_the_curve([1, 2, 3, 4, 5]) ➞ [3, 3, 3, 3, 3]

flatten_the_curve([0, 0, 0, 2, 7, 3]) ➞ [2, 2, 2, 2, 2, 2]

flatten_the_curve([4]) ➞ [4]

flatten_the_curve([]) ➞ []

Notes

• Round averages to 1 decimal point.
• Return an empty list if given an empty list (see example #4).
