Why there are several versions of the same quotation in Alice in Wonderland? Where are they taken from?

I recently came across some differences in the same quotation from the book. I know that the first one is the original one, but why it is paraphrased? Where do the others come from? Here they are:

1. “Would you tell me, please, which way I ought to go from here?"

"That depends a good deal on where you want to get to."

"I don't much care where –"

"Then it doesn't matter which way you go.”

2. “Alice came to a fork in the road. 'Which road do I take?' she asked.

'Where do you want to go?' responded the Cheshire Cat.

'I don't know,' Alice answered.

'Then,' said the Cat, 'it doesn't matter.”

3. “Cat: Where are you going?

Alice: Which way should I go?

Cat: That depends on where you are going.

Alice: I don’t know.

Cat: Then it doesn’t matter which way you go.”
