![]() If cari is found in the list, ketemu is set to True and a positive response is printed out. is ketemu True? No, go to else state -> prints "Value: 4 not found"įrom this step-by-step analysis, we can see the logic behind this snippet of code. In this example, cari was set to 4, and ketemu remained False. ![]() is ketemu True? Yes -> prints "Value: 7 ada" In this example, cari was set to 7, and ketemu was set to True. It's important to note that in Python the following two statements have the same meaning. Let's use the previous examples to find out what happens here. If cari is not in the list, this means that ketemu can remain False without any extra work.Īt this step, we want to tell the user whether we have found cari in list a. If cari is in the list, this logic structure allows us to set ketemu to True without replacing it with False. Let's run through an second example : let cari be 4, ketemu be False Is cari = 11? No -> ketemu remains True and is not replaced with False Is cari = 9? No -> ketemu remains True and is not replaced with False Is cari = 7? Yes -> ketemu is changed to True Let's run through an example : let cari be 7, ketemu be False The reason that ketemu is originally set to False and changed to True lets us know for certain whether cari is in a. We are trying to prove whether cari is in the list, and if it is, ketemu is set to True. In this step, we are checking to see if cari is in the list a, so we cycle through each of the elements in the list. Step 2: Check for cari for i in range(0, len(a)): ketemu is False until proven otherwise, and we will see why that's important when looping through the a values. This final initialization is crucial for understanding the code. Finally, we set a default value for ketemu. First, the list we want to check to see if cari is in is defined. This is the part of the code where initial values are set. Let's go step-by-step through this code and see if we can analyze what is happening. Assume they are:- array, n, and keyĭ) If the match is found then return the position.Į) Else repeat the process until the end of the array.į) After traversing the array If the match is not found then return -1.Tl dr - The code assumes that cari is not in the list until proven otherwise. ![]() The procedure to find an element in a given array or list through linear search,Ī) Take array, size of the array, and the search key. Therefore return -1 which means the search key is not available. It won’t match with 50, 90, 30, 70, 60, and finally reached the end of the array. Traverse through the array and compare with each element. It was the situation where the search key exists in the array, now let us assume when the search key is not available. The next element of the array is 30 which is equal to the search key 30 therefore return the index of the current element of the array. The next element is 90, but it is also not equal to 30 therefore move to the next element. ![]() The first element of the array is 50, but 50 is not equal to 30 therefore move to the next element. Let us understand it through an example:- Given array = Īssume the search key = 30 Then traverse through the array and compare with each element. If the match is found then it returns its index, else it will reach the end of the array or list which means the search key is not available. If the first element is not equal to the search key then it will compare with the next element, and so on until the match is found or the end of the array. It begins the search by comparing the search key and the first element of the array/list. In Linear search, finds the index or location of search in the given array. Linear search or Sequential 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. Linear search or Sequential search in data structure | The Linear search or Sequential search is a method to finding an element within a given list or array. ![]()
