Space complexity is constant O (1) as we only need to store indices for the search in the list. brickseek walmart xbox controller

"Webb12 juli 2024 · Binary search is used because it has a time complexity of O (N) for a sorted array. If we follow sequential access of Linked List, then it will take O (N) time to find the middle element. With this, the overall time complexity of Binary Search on Linked List will become O (N * logN). This will slower than linear search. " - Proving time complexity of skip list search
