WebSep 27, 2024 · The Binary Search algorithm works as follows: Set the search space equal to the sorted array Take the middle element of the search space and compare it to the target value. - If the target equals the middle element, you have found the target value. Return the index of the middle element and terminate the function. 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. shwe pyi 115 miles hotel

WebAnalysis. Linear search runs in O (n) time. Whereas binary search produces the result in O (log n) time. Let T (n) be the number of comparisons in worst-case in an array of n elements. Hence, T ( n) = { 0 i f n = 1 T ( n 2) + 1 o t h e r w i s e. Using this recurrence relation T ( n) = l o g n. Therefore, binary search uses O ( l o g n) time.
