Thank you We speak and here's your shmoop usually brought

a little sour We're starting a new business that ship's

state of the economy We're in a bit of well
- 00:22
pickle and we want to generate more revenue We've written
- 00:25
a program that sorts and ship pickles in the following
- 00:27
quantities and prices based on order size program takes the
- 00:31
order sizes and imager input parameter and outputs The total
- 00:34
cost of the order Four dollars on nine cents Reach
- 00:37
pickle upto Five pickles Two bucks for each additional pickle
- 00:41
beyond five but not exceeding twelve and a dollar for
- 00:44
each additional pickle after twelve What's the smallest set of
- 00:48
orders that adequately tests our program Here's the thing here
- 00:53
is like rain Yeah think about this All right So
- 00:58
for this problem we want a set of numbers that
- 01:00
test each possible case for each range We want to
- 01:03
test the lower limit A number in the middle and
- 01:05
the upper limit For example the first range Where there
- 01:09
Should be no differential in the cost of pickles is
- 01:11
from zero to five pickles Thus we wanna test zero
- 01:14
pickles a number in between three pickles and five pickles
- 01:19
This'll adequately test the first price range for the next
- 01:22
price range We test the lower and upper limits a
- 01:25
five and twelve and a middle number seven Lastly we
- 01:28
want to test the upper price range the lower limit
- 01:30
being twelve in this case and unique as all we
- 01:33
need to do adequately tested is input a number greater
- 01:36
than twelve Well all pickles after twelve should be the
- 01:40
same cost so we can pick any number above twelve
- 01:43
to test our last case But we have test cases
- 01:47
with zero three five seven twelve fifteen pickles and that
- 01:51
makes our answer choice D Next time we'll cover the 00:01:53.848 --> [endTime] process of making pickles not a big deal
