Given a sorted integer array, remove duplicate elements. For each group of elements with the same value do not keep any of them. Do this in-place, using the left side of the original array and and maintain the relative order of the elements of the ar…
Given an unsorted integer array, remove adjacent duplicate elements repeatedly, from left to right. For each group of elements with the same value do not keep any of them. Do this in-place, using the left side of the original array. Return the array…
