#SEQUENTIAL SEARCH CODE CODE#
Print('Target not found in the list') Source Code def sequentialSearch(target, List): Print('Target found at index :',answer,'in',iterations,'iterations') Then simply check if the answer is -1 which means we can’t find the element in the given list otherwise print the position of that element along with the global iterations variable.
Now, let’s create a custom list contains different integers in it which we need to pass to the above function from where we have search for the target.Īlso, create a target variable which we need to pass to the function which is to be searched in the given list.Īnd let’s store the position returned by the function in another variable call it as the answer. So for traversing through the list, we are gonna use a while loop to traverse till the length of the given list.Īnd we compare the target element with the list element at the current index at each iteration and return the position if the element is found otherwise return -1 as a result. So for that let’s declare variable position and initialize it to 0 which keep the track of the index element.Īlso declare a new global variable named iterations which keep record how many elements we traverse before finding the position of that target element. If the target element exists in the given list then we simply keep the position variable to store at which index the element is present in the list and the return that position to the callback function otherwise we simply return -1 as not found an error in the list. Read => Program to illustrates a simple stopwatch So the logic we are going to implement in this sequential search is that we traverse through each and every element of the given list and check every element of the list with the target element. Now, let’s create a new function named sequential search which accepts two parameters as an argument, first is the target which we need to find and second is the list from which we need to find that target. Linear search is usually very simple to implement and is practical when the list has only a few elements, or when performing a single search in an unordered list. It sequentially checks each element of the list until a match is found or the whole list has been searched. In computer science, a linear search or sequential search is a method for finding an element within a list. Hi, in this tutorial, we are going to write a program that illustrates or an example for sequential search or linear search in Python.
