Create a function that takes a list of numbers and return its median. If the input list is even length, take the average of the two medians, else, take the single median.

Examples

median([2, 5, 6, 2, 6, 3, 4]) ➞ 4

median([21.4323, 432.54, 432.3, 542.4567]) ➞ 432.4

median([-23, -43, -29, -53, -67]) ➞ -43

Notes

• Input can be any negative or positive number.
• Input list will contain at least four numbers.
• See Resources tab for info on calculating the median.
