The steps are: Step 1: Examine the current element in the list. Step 2: If the … WebFollowing is a step-by-step approach employed to implement Linear Search Algorithm. Step 1: First, read the search element (Target element) in the array. Step 2: In the second step compare the search element with the first element in the array. Step 3: If both are matched, display "Target element is found" and terminate the Linear Search function. WebGiven a sorted integer array containing duplicates, count occurrences of a given number. If the element is not found in the array, report that as well. For example, Input: nums [] = [2, 5, 5, 5, 6, 6, 8, 9, 9, 9] target = 5 Output: Target 5 occurs 3 times Input: nums [] = [2, 5, 5, 5, 6, 6, 8, 9, 9, 9] target = 6 Output: Target 6 occurs 2 times polyhedron 12 faces

There are two exit conditions for this recursion: If the search element is not found, return -1, i.e., start becomes greater than the end. If the element is found, return the mid index. polyhedron 22 scribdWebBinary Search is one of the fastest searching algorithms. It is used for finding the location of an element in a linear array. It works on the principle of divide and conquer technique. Binary Search Algorithm can be applied only on Sorted arrays.

In this approach, the element is always searched in the middle of a portion of an array. Binary search can be implemented only on a sorted list of items. If the elements are not sorted already, we need to sort them first.

WebDec 18, 2016 · Steps: 1.Find the middle value.
