More efficient than a linear search, the binary search algorithm operates inO(log n)time complexity. Bisect_left Thebisect_left()function from Python’s built-inbisectmodule is an alternative to the binary search algorithm. It finds the index of where the target element should be inserted to m...
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,...
We sacrifice theoretical time complexity for practical performance. The size of the subarrays is a trade-off. You can modify how big you want to subarrays by setting the load_factor. The default is set to DEFAULT_LOAD_FACTOR = 1000. The subarray is split when its size is 2*load_factor...
The loop exits when left > right, and right will point to the last occurrence of the target or the last element smaller than the target if the target is not found. 4. Time & Space Complexity Analysis: Time Complexity: O(logn) Space Complexity: O(1) ...

The runtime complexity for indexing a sorted list is O(log(n)) while it is O(1) for Python’s built-in list data type. Indexing a sorted list requires building and maintaining a positional index which is not built if not necessary. The index is fast and light on memory overhead but...
