Web1 day ago · Step 1 − Create a function to implement a binary search algorithm. Step 2 − Inside the function, first we find the lower bound and upper bound range of the given array. Step 3 − Run a while loop till LBound<=UBound. Step 4 − Now find the middle value of the given range. And check if the middle value is equal to the key element. WebBinary search is a fast search algorithm with run-time complexity of Ο (log n). This search algorithm works on the principle of divide and conquer. For this algorithm to work properly, the data collection should be in the sorted form. Binary search looks for a particular item by comparing the middle most item of the collection.

In computer science, binary search, also known as half-interval search, logarithmic search, or binary chop, is a search algorithm that finds the position of a target value within a sorted array. Binary search compares the target value to the middle element of the array. If they are not equal, the half in which the target cannot lie is eliminated and the search continues on the remaining half, again … WebGiven the array nums after the possible rotation and an integer target, return the index of target if it is in nums, or -1 if it is not in nums.
