Problem 2.3 from SCHAUM’S OUTLINE OF Principles of COMPUTER SCIENCE

Count the primitive operations in your algorithm to find the mean.
What is the order of growth of your mean algorithm?



setup 4
loop 5 * length (length = n, the count of numbers to be averaged)
return 2


Order of growth :  Θ( n )

Write pseudo code for finding the mean of a set of numbers.

mean( list_of_numbers )
length <-- length of list_of_numbers
index <-- 1
sum <-- 0
while index <= length {
sum <-- sum + list_of_numbers[index]
index <-- index + 1
}
return sum / length

example input :

mean ( 1 2 3 4 )
length <-- 4
index  <-- 1
sum    <-- 0
list_of_numbers[1] = 1
list_of_numbers[2] = 2
list_of_numbers[3] = 3
list_of_numbers[4] = 4
