WebSep 19, 2024 · Binary search is a searching algorithm that uses divide and conquer approach to make searching efficient. To apply binary search on any data structure including arrays, the data must be sorted in an order. Binary search can not be applied to unsorted data set. Now see the working of binary search stepwise. WebBinary search is a search algorithm that finds the position of a key or target value within a array. Binary search compares the target value to the middle element of the array; if they are unequal, the half in which the target cannot lie is eliminated and the search continues on the remaining half until it is successful.
