WebFeb 18, 2024 · A binary search is an advanced type of search algorithm that finds and fetches data from a sorted list of items. Binary search is commonly known as a half-interval search or a logarithmic search It works by dividing the array into half on every iteration under the required element is found. WebBinary search is an efficient algorithm for finding an item from a sorted list of items. It works by repeatedly dividing in half the portion of the list that could contain the item, until you've narrowed down the possible locations to just one. We used binary search in the guessing game in the introductory tutorial.

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. WebBinary search is a searching algorithm which uses the Divide and Conquer technique to perform search on a sorted data. Normally, we iterate over an array to find if an element is present in an array or not. greenslopes hospital fax
