This Question: shows a

typical use case for the split command: Splitting a string into words. An additional difficulty is that

you

are

asked

to

count

the

words.

Although

it

is

tempting

to

use

the

count method here, the size method (as in: size of an array) is actually the correct one to use.

Familiarize yourself with the split and the size methods using the linked documentation below.
