Permuted Index explanation.

[Terviseks]

Hello everyone.

I am currently learning C++ from a book:
"Accelerated C++ Practical Programming by Example"

There I have a exercise that requires me to write a program to produce a permuted index. I tried to google some answers for what is permuted index but didn't find any really simple explanations but I did find some.

Can anyone tell me if I have understood the principle of permuted index correctly?

My example:

Phrase: The big blue sky
Permuted index:

_______The big blue sky
____The big blue sky
The big blue sky
__________The big blue sky


Thank you for helping.
