      public int removeDuplicates(int[] nums) {
          int k = 0;
          for (int x : nums) {
              if (k == 0 || x != nums[k - 1]) {
                  nums[k++] = x;
              }
          }
          return k;
      }
  }

C++

• class Solution {
  public:
      int removeDuplicates(vector<int>& nums) {
          nums.erase(unique(nums.begin(), nums.end()), nums.end());
          return nums.size();
      }
