If n is the length of the array at the first iteration, then at the second iteration, the length of the array will be n/2. Again dividing by half in the third iteration will make the array’s length = (n/2)/2=n/ (2^k). flowers for long distance relationships

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. … WebOct 17, 2024 · binary search: average case is log n, best is 1 (middle item = desired item), and worst is log n (desired item not in list) selection sort: average case is n 2, best is n 2, and worst is n 2; selection sort: average case is n log n, best is n log n, and worst is n log n.
