The algorithm as a whole still has a running time of O(n2) on average because of the series of swaps required for each insertion.

WebIn binary search, without doing any analysis, we can see that the array is divided into half its initial size each time. So even in the worst case, it would end up searching only log2n log 2 n elements. Thus, binary search is a O(lgn) O ( lg n) algorithm. We are also going to mathematically see this running time later in this chapter. WebAverage case analysis of binary search . 1. A rudimentary (and incorrect) analysis of the average case ...

WebHere's the pseudocode for binary search, modified for searching in an array. The inputs are the array, which we call array; the number n of elements in array; and target, the number being searched for. The output is the index in array of target: Let min = 0 and max = n-1. …

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 would be O (log N), where N is number of nodes.
