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...

Optional key argument defines a callable that, like the key argument to Python’s sorted function, extracts a comparison key from each value. The default, none, compares values directly. Runtime complexity: O(n*log(n)) >>> ss = SortedSet([3, 1, 2, 5, 4]) >>> ss SortedSet([1,...

I have tried this solution that uses recursion to try to solve the problem, it gives correct answers for the first couple of attempts, but after it just takes too long, i need help :c Is a code from python3: def revision(array): ...
Your algorithm’s runtime complexity must be in the order of O(log n). Example 1: Input: nums = [4,5,6,7,0,1,2], target = 0 Output: 4 1. 2. Example 2: Input: nums = [4,5,6,7,0,1,2], target = 3 Output: -1 ...
Your algorithm’s runtime complexity must be in the order ofO(log n). If the target is not found in the array, return [-1, -1]. Example 1: AI检测代码解析 Input: nums = [5,7,7,8,8,10], target = 8 Output: [3,4] ...

的确python自带的sort函数非常诱人,只需要一步到位,非常的偷懒和方便 nums1=sort(nums1[0:m]+nums2[0:n]) 但是考虑到这是算法题,python自带的sort函数,时间复杂度是O(nlogn),即O((m+n)log(m+n)),是长于题目要求O(m+n)的。
