find(nums[i]) == uniqueSet.end()) { uniqueSet.insert(nums[i]); } } for (auto element : uniqueSet) { cout << element; } return uniqueSet.size(); } }; 上述代码中,我们使用uniqueSet.size()来获取uniqueSet中不重复元素的个数,然后通过遍历un

Using binary search to find the start index of the k window. A obvious characteristic of the final state is that the difference of left element and x should always be less than or equal to that of the right element. So we can use x - arr[mid] > arr[mid + k] - x as the binary...
