Hello GoodTecher,

Thank you for the solution.

I was just trying to dry run your explanation on input [1, 2, 2, 2] and I am confused why [2, 2, 2], [1, 2, 2, 2] are being added to the final result.

Line 21 in your code should make sure that [1, 2, 2, 2 ] and [2, 2, 2] are not added to the final result right?

I appreciate your help.

Can you please add leetcode questions permutations & permutations || in your playlist?

Thanks for the helpful videos!
Did you use i!=startIndex to make sure we don't get Out of Bound Exception right ? I mean while i/startIndex=0. Or is there any other purpose of it ?

What a mess. Can't understand half of what the guy is saying. Could very well be he's talking about fishing tuna and I wouldn't have guessed it.
