Writing Functions WS
1. Write a function named Summation that is passed an Integer parameter named intNum. The function must compute and return
the sum of the numbers 1 through intNum. For example, if intNum is 5, then 15 is returned since 1 + 2 + 3 + 4 + 5 is 15.
2. Write a function named Min that accepts three Integer parameters. The function must return the smallest of the three
parameters. You may choose the names of the parameters.
3. Write a function named Median that the median value of three Integer parameters. For example, if the three parameters are 12, 9, and 3 then the value 3 is returned because 3 is between -9 and 12. You may choose the names of the parameters. You may
assume that all three parameters are unique values and different. It is recommended that you use an If ElseIf statement.
