Thanks for contributing an answer to Stack Overflow! data element and repeats. what is the reason for java.lang.stackoverflowerror in this code? Notice that the actual process of searching the array is the same for both the iterative and recursive functions. You need to write a recursive function such that if the element is found in the given array, the index of the element is returned and if the element is not found in the array, -1 is returned.

Is it possible for rockets to exist in a world that is only in the early stages of developing jet aircraft? 20% I wanted to see if anyone could point me in the right direction on this, I feel like I am overlooking something very simple, the main is calling the search method on a list of about 45,000 words, which I believe is the problem, my code works for words that are in the first 6 or so thousand words in the list, but after that it encounters a StackOverflow error and crashes. Thus, 3 is returned from the function and "Element 4 found at index 3" is displayed on the output. Let's move onto binary search. Linear search operates by looking sequentially through data, comparing the current element to the search element. Step 1 - START Step 2 - Declare a string array namely input_array, two integer namely key_element and index Step 3 - Define the values.

If any element is found equal to the key, the search is successful and the index of that element is returned. else return middle; However, the shortcomings of Linear Search are obvious when the array in question contains tens of thousands of elements. You then compare the head, if it is equal to your value, you return the index so far, otherwise, you call the recursive function with the tail and the index incremented. Yes it is O(n). In this case, to implement a recursive version of the function, we need to add a third parameter, index, to tell us where to check in the array. Of course, binary search can be done iteratively as mentioned: But intuitively it makes more sense recursively. Call the function recursively until the right index is less than the left index.

If l is supposed to be unrelated to the class, either change @classmethod to @staticmethod (the latter does not implicitly receive the type as the first argument) or add a cls argument in front of l. If the goal is to process an instance attribute, then I'd suggest making the top-level function an instance method, with a recursive helper method (that's either class or static). For example: There are only three cases to worry about: I put "first" in quotes because while it is elegant to pass the tail of the input list to each recursive call, the overhead of constructing the tail makes it inefficient to do so.

Linear Search is defined as a sequential search algorithm that starts at one end and goes through each element of a list until the desired element is found, otherwise the search continues till the end of the data set. Step 4 - Iterate through the array. I have two base cases, which are the end of the array, in which case we throw ItemNotFoundException, and if the word is found, in which case we return the index at which the item was located. In every iteration, associate the target value with the given value of the list/array. We will find recursive functions more useful later on in the module.
