Python’s built-insorted()function enables programmers to sort a list efficiently and easily. On the other hand, thelist.sort()method provides an in-place sorting mechanism. Additionally, Python allows forcustom sortingusing thekeyparameter in these functions, enabling more advanced sorting scenarios...

i usedunordered_map<>by while adding the elements in the unordered_map<> when the add operation is processed. But i gotTLE at test 36. Later when i checked other's solutionthey used ordered_map<>and used the.find()function to check whether the element is added to the set or not. An...

If the last number in the sorted array is not the N (size of the array), the missing number can be simply set to N. This approach uses O(1) constant space. Set It is straightforward to use set (or preferably the unordered_set). The space complexity is O(N) and the time complexit...
