Answer 1

your code is checking to see if the array has a duplicate value anywhere in the array, starting at i+1.

Answer 2

here is what you want. you had a few errors,
1. you didnt finish the comment at the bottom with a */, so there was an error.
2. you shouldnt loop through the entire array again, just a simple "if arr[i] == arr[i+1]" will work to check if they are next to eachother.
3. the code structure made me v uncomfortable but thats ok 😂

be sure to read the comment I left below yours
