- We'll take 'start' variable, where we'll fill value if it's new element (if a[i] != a[i-1])
- At last we'll return 'start' as anaswer as till now we've all unique elements & we've pul all unique elements at the start of array

Well explanation👍. Is it really removing all duplicates from array? I think no. Because the remaining values still spoils the array with duplicates. Can we keep it in separate array and assign it back to the old array or just remove the remaining elements from start. Then we could say the array has only unique values. What about your opinion on this?
