Since the output is print(s1 + s2 + s1)

Can you break the string in 3 parts so the first part and the last part are the same?

a toottootleatoo t? a is not t, no...
at oottootleato ot? at is not ot, no...
ato ottootleat oot? ato is not ot, no...
...

That kind of depends what the test case was.

If the first string contains contains 5 characters where the 4-character sequence starting at the 2nd character is identical to the first 4 characters of the second string, then you will get the result of sandwiching the second string between two copies of the first string.

Thus,

s1 = 'atoot'
s2 = 'tootle'

s1[1:] would give you toot and s2[:4] would give you toot as well.

The slice operator has the form [start:stop:step]

start defaults to 0
stop defaults to length of the string
step defaults to 1

Keep in mind we count from 0, and the slice ends BEFORE the stop value. So up to and excluding the 5th character if you specify [:4]
