Pseudo-code

sum ? count ? 0 { sum = sum of numbers;

count = how many numbers are entered? }

min ? ? { min to hold the smallest value eventually }

max ? ? { max to hold the largest value eventually }

for each num entered,

increment count

sum ? sum + num

if num < min then min ? num

if num > max then max ? num

ave ? sum/count

To find average, min and max among a list.
