HW 1/12/2017   Assorted small pieces: assignment, conditional, sequence, easy loops

Due: 1/17/2017

All functions should be put in one single script.  Functions should have the indicated names.
You don't have to do any error checking.

Turn in:
  Hard copy of script
  Demo of all functions
  
  
(1) min1 (a, b)
parameters: a, b are numbers
return the minimum value
CONSTRAINT:  Must use conditional, do not use Python's built-in min()

(2) max1 (a, b)
parameters: a, b are numbers
return: maximum value
CONSTRAINT: Must use conditional, do not use Python's built-in max()

(3) minmax1(a, b)
parameters: a, b  are numbers
return: (minimum value, maximum value)

(4) average4(a, b, c, d)
parameters: a, b, c, d are numbers
return: average

(5) findDiameter(radius)
parameter: radius is a number
return: diameter

(6) findCircleArea(radius)
parameter: radius is a number
return: area of circle

(7) countUp(max)
parameter: max is number (integer)
return: output the numbers from 1 to max -- e.g., 1 2 3 ... max

(8) countDown(max)
parameter: max is number (integer)
return: output the numbers from max down to 0.

(9) sumUp(a, b)
parameters: a, b are integers, a < b
return: the sum of all integers between (and including) a and b
e.g. sumUp(3, 5)  returns 12

(10) multiples(a)
parameter: a is number, a > 0
return: output the multiples of a: a*0, a*1, a*2, ... a*12
e.g. multiples(4) returns 0  4  8  12  16  20  ... 48
