We speak student! And here's your Shmoop dou jour, brought to you by, the student who

00:07

had an open perspective. He was a dilated pupil. Alright what would be the best set of inputs, [man meditating in a forest]

00:13

to make sure the following code functions, as expected. [mumbling]

00:17

Alright well here are your potential answers. Okay, well here we go. We must [equations and multiple choice answers]

00:28

build a set here, that adequately test each range of numbers. I'll fully test a

00:33

certain range, we must in put the lower limit and the upper limit. Well first of

00:39

all we gotta start with zero. It's a number that should always be included in [someone making the ok sign with their hand]

00:42

test inputs, because of its unique property's. Next we need to test whether

00:47

the lower than, C, case works. So we should put in a number less than 70, 69 should

00:53

work. All right now we can test the C case. We have to put in the lower and

00:57

upper limits 70 and 79. The next test case is the, B range, with lower and upper [equations on chalkboard]

01:04

limits being, 80 and 91. And finally we can test the A range case, so we should put

01:10

in 92. And just like we put in a number below the lowest case, we should put in a

01:15

number higher than the highest case. Well anything above 92 should work. Say a

01:20

hundred and ten and we've built the following set, which leaves us with B.

01:24

Well don't worry you can only shoot for an A next time. [man in classroom crying]
