![]() ![]() If there is no match or the search element is not present in the given array, return -1.If the element does not match, then move to the next element. ![]() If the element matches, then return the index of the corresponding array element. ![]() In each iteration of for loop, compare the search element with the current array element, and. First, we have to traverse the array elements using a for loop.The steps used in the implementation of Linear Search are listed as follows. The worst-case time complexity of linear search is O(n). It is widely used to search an element from the unordered list, i.e., the list in which items are not sorted. If the match is found, then the location of the item is returned otherwise, the algorithm returns NULL. In Linear search, we simply traverse the list completely and match each element of the list with the item whose location is to be found. Linear search is also called as sequential search algorithm. So, here we will discuss the popular searching technique, i.e., Linear Search Algorithm. Two popular search methods are Linear Search and Binary Search. If the element is present in the list, then the process is called successful, and the process returns the location of that element otherwise, the search is called unsuccessful. Searching is the process of finding some particular element in the list. It operates looping on each element O(n) unless and until a match occurs or the end of the array is reached.In this article, we will discuss the Linear Search Algorithm. It is a simple algorithm that searches for a specific item inside a list. The performance of the linear search can be measured by counting the comparisons done to find out an element. Suppose the element to be searched is '46', so 46 is compared with all the elements starting from the 0 th element, and the searching process ends where 46 is found, or the list ends. The list given below is the list of elements in an unsorted array. In case of a sorted list searching starts from 0 th element and continues until the element is found from the list or the element whose value is greater than (assuming the list is sorted in ascending order), the value being searched is reached.Īs against this, searching in case of unsorted list also begins from the 0 th element and continues until the element or the end of the list is reached. This method can be performed on a sorted or an unsorted list (usually arrays). In this technique of searching, the element to be found in searching the elements to be found is searched sequentially in the list. ![]() This is the simplest method for searching. Some of the standard searching technique that is being followed in the data structure is listed below: Any search is said to be successful or unsuccessful depending upon whether the element that is being searched is found or not. Searching is an operation or a technique that helps finds the place of a given element or value in the list. In this chapter, you will get to know the basic concepts of searching that are used in the data structure and case of programming also. If the data is kept properly in sorted order, then searching becomes very easy and efficient. You often spend time in searching for any desired item. The process of identifying or finding a particular record is called Searching. This chapter explores various searching techniques.
