Median of Three
Given an iterable of ints , create and return a new iterable whose first two elements are the same as in items, after which each element equals the median element in the list of the three elements from the original list. This list of three ends on the current position, first two elements are going just before the third element.
Wait...You don't know what the "median" is? Go check out the separate "Median" mission on CheckiO.
Input: Iterable of ints.
Output: Iterable of ints.
Example:
assert median_three([1, 2, 3, 4, 5, 6, 7]) == [1, 2, 2, 3, 4, 5, 6] assert median_three([1]) == [1]
The mission was taken from Python CCPS 109 Fall 2018. It’s being taught for Ryerson Chang School of Continuing Education by Ilkka Kokkarinen
