cant understand how it works, in a first if we compare first and last element in array, and in case if it aint equal moving forward.. but how it works when array is like [ 0, 0, 1, 0, 0 ] here are the first and last element are the same

for this time i dont know that the Set can work so, it's a real magic for me, it's realy awesome

what method slice doing here?

thanks, i gas i dumb i dont understand anything(

What is "Set"? i didn't find about it nothing.
