I was solving the problem :1732D1 - Balance (Easy version). And my solution was same as i keep the track of thekth-MEXof thexthelement when ever the request has been made. So for checking whether the kth element is present in the set or not, i usedunordered_map<>by while adding ...
Your runtime complexity should be less thanO(n2). There is only one duplicate number in the array, but it could be repeated more than once. 思路1使用map存储元素及其对应索引。 classSolution {public:intfindDuplicate(vector<int>&nums) {if(nums.empty())return0; unordered_map<int,int>m;for(...
What is the time complexity of your modified solution? What is the most time-consuming part and memory consuming part of it? How to optimize? How to make sure the duplicated files you find are not false positive? 思路: 首先就是将字符串处理成完整路径的形式,然后用map统计相同内容的文件路径。
