When the union is reporting about the latest salary negotiations they are presenting the average salary, the median salary, and the salary gap for the workers that they represent. Write a program salary_revision. py that reads an arbitrary number of salaries (integers) and then reports the median and average salaries, and the salary gap. All of them should be integers (correctly rounded off). By salary gap we mean the difference between the highest and lowest saleries. The median salary is the middle salary (or average of the two middle salaries) when all saleries have been sorted. The easiest way to sort a list is to use the sort method in the list class.

Two different executions might look like this:

Provide salaries: 21700 28200 26300 25100 22600 22800 19900
Median: 22800
Average: 23800
Gap: 8300

Provide salaries: 22100 29800 27300 25400 23100 22300
Median: 24250
Average: 25000
Gap: 7700
