"WebFor binary search, this is 0.5 × 0.5 + 0.5 × 0.5 = 0.5 (we always remove half the list). For ternary searches, this value is 0.666 × 0.333 + 0.333 × 0.666 = 0.44, or at each step, we will likely only remove 44% of the list, making it less efficient than the … " - Binary search average time complexity proof

WebThe time complexity of creating these temporary array for merge sort will be O(n lgn). Since, all n elements are copied l (lg n +1) times. Which makes the the total complexity: O(n lgn) + O(n lgn) = O(2n lgn). And we know that constants doesn't impact our complexity substantially. So time complexity will still be O(n lgn). WebSo overall time complexity will be O (log N) but we will achieve this time complexity only when we have a balanced binary search tree. So time complexity in average case …
