LC 26. Remove Duplicates from Sorted Array

https://leetcode.com/problems/remove-duplicates-from-sorted-array/description/?envType=study-plan-v2&envId=top-interview-150

class Solution {
public:
    int removeDuplicates(vector<int>& nums) {
        int idx = 1;
        for (int i = 1; i < nums.size(); i++) {
            if (nums[i] == nums[i - 1]) continue;
            nums[idx++] = nums[i];
        }
        return idx;
    }
};

Time Complexity: O(n)
Space: O(1)

沒特別想說的
