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 is the identity function. Runtime complexity: O(n*log(n)) >>> from operator import neg >>> skl = SortedKeyList(key=neg) >>> skl ...
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...
The time complexity of the above solution isO(m + n), wheremis the total number of nodes in the first BST andnis the total number of nodes in the second BST. The additional space used by the program isO(x + y), wherexis the height of the first tree, andyis the height of the s...
