## Session 1: Median

Suppose the variables a, b and c contain a natural number.

Write a code fragment that assigns to the variable median the median value of these numbers.

As a reminder, the median of three values is the value such that there is exactly one value lower than (or equal to) it and one value higher than (or equal to) it.

##### Implementation
a = ... #variable to evaluate
b = ... #variable to evaluate
c = ... #variable to evaluate
median = ... #store in this variable the median of the three variables
