Alter insertion sort below to sort a list of strings instead of numbers. It shouldn't return anything - it should sort the list "in place". The sorting should ignore case. For example "Zebra" should come after "apple", "maRker" should come after "marble", etc. Name this function string_sort. After calling this function, the list that was passed in should now contain the exact same strings it did before, but in sorted order.
def insertion_sort(a_list):
"""
Sorts a_list in ascending order
"""
for index in range(1, len(a_list)):
value = a_list[index]
pos = index - 1
while pos >= 0 and a_list[pos] > value:
a_list[pos + 1] = a_list[pos]
pos -= 1
a_list[pos + 1] = value

- String replacement is read from input. Then, sentence is read from input. If replacement is in sentence, then: Output 'Located at index: ' followed by the index of the last occurrence. Create a string from sentence with the first two occurrences of replacement replaced by '5' and output sentence on a newline.arrow_forwardComplete the function that computes the length of a path that starts with the given Point. The Point structure = point on the plane that is a part of a path. The structure includes a pointer to the next point on the path, or nullptr if it's the last point. I'm not sure how to fill in the '?'; especially the while loop I'm not sure how to implement the condition for that.arrow_forwardData Structure and algorithms ( in Java ) Please solve it urgent basis: Make a programe in Java with complete comments detail and attach outputs image: Question is inside the image also: a). Write a function to insert elements in the sorted manner in the linked list. This means that the elements of the list will always be in ascending order, whenever you insert the data. For example, After calling insert method with the given data your list should be as follows: Insert 50 List:- 50 Insert 40 List:- 40 50 Insert 25 List:- 25 40 50 Insert 35 List:- 25 35 40 50 Insert 40 List:- 25 35 40 40 50 Insert 70 List:- 25 35 40 50 70 b).

- page WITH Write a function swap() that takes as input a list of items. If the list is not empty, it swaps its first and last elements. The function does not return anything. Sample result with list1= ['all', 'good', 'things', 'must', 'end', 'here'] after the function call list1 becomes: ['here', 'good', 'things', 'must', 'end', 'all'] Write 2 assert statements. www def swap(...): param: ... returns None if_name__ == "__main__": assert ... #TODO: complete your own assertarrow_forwardBinary Search of Strings1. Write a version of the selection sort algorithm presented in the unit, which is usedto search a list of strings.2. Write a version of the binary search algorithm presented in the unit, which isused to search a list of strings. (Use the selection sort that you designed aboveto sort the list of strings.)3. Create a test program that primes the list with a set of strings, sorts the list, andthen prompts the user to enter a search string. Your program should then searchthe list using your binary search algorithm to determine if the string is in the list.Allow the user to continue to search for strings until they choose to exit theprogramarrow_forwardhave been given a singly linked list of integers. Write a function that returns the index/position of integer data denoted by 'N' (if it exists). Return -1 otherwise. Note :Assume that the Indexing for the singly linked list always starts from 0.Input format :The first line contains an Integer 'T' which denotes the number of test cases. The first line of each test case or query contains the elements of the singly linked list separated by a single space. The second line contains the integer value 'N'. It denotes the data to be searched in the given singly linked list. Remember/Consider :While specifying the list elements for input, -1 indicates the end of the singly linked list and hence -1 would never be a list element. Output format :For each test case, return the index/position of 'N' in the singly linked list. Return -1, otherwise. Output for every test case will be printed in a separate line. Note:You do not need to print anything; it has already been taken care of. Just implement…arrow_forward
- Write a function called find_duplicates which accepts one list as a parameter. This function needs to sort through the list passed to it and find values that are duplicated in the list. The duplicated values should be compiled into another list which the function will return. No matter how many times a word is duplicated, it should only be added once to the duplicates list. NB: Only write the function. Do not call it. For example: Test Result random_words = ("remember","snakes","nappy","rough","dusty","judicious","brainy","shop","light","straw","quickest", "adventurous","yielding","grandiose","replace","fat","wipe","happy","brainy","shop","light","straw", "quickest","adventurous","yielding","grandiose","motion","gaudy","precede","medical","park","flowers", "noiseless","blade","hanging","whistle","event","slip") print(find_duplicates(sorted(random_words))) ['adventurous', 'brainy', 'grandiose', 'light', 'quickest', 'shop', 'straw', 'yielding']…arrow_forwardWrite a version of the binary search algorithm that can be used to search a list of strings. (Use the selection sort that you designed to sort the list.)arrow_forward1.Given the argument passed to the function is a list containing integer values, what does the function return def mystery1(someListOfValues: list):total = 0for value in someListOfValues:total += valuereturn total/len(someListOfValues) 2. The function below is to find the largest value in a list passed by parameter. Does it work as intened (yes or no)? If not give an example of an argument it would not work for. def maxValue(someListOfValues:list):"""returns the largest value the list passed by parameter"""value = 0for num in someListOfValues:if num > value:value = numreturn value 3.Write a function called loadNames() that will open a file called names.txt and build a list of its contents and return it. Function Call: names = loadNames()print(names) Sample ouput: ['Nolan Rafaj\n', 'Brandon Brzuszkiewicz\n', 'Amanda Vozari\n', 'Chase Harper\n', 'Bryce Conner']arrow_forward
- PYTHON Complete the function below, which takes two arguments: data: a list of tweets search_words: a list of search phrases The function should, for each tweet in data, check whether that tweet uses any of the words in the list search_words. If it does, we keep the tweet. If it does not, we ignore the tweet. data = ['ZOOM earnings for Q1 are up 5%', 'Subscriptions at ZOOM have risen to all-time highs, boosting sales', "Got a new Mazda, ZOOM ZOOM Y'ALL!", 'I hate getting up at 8am FOR A STUPID ZOOM MEETING', 'ZOOM execs hint at a decline in earnings following a capital expansion program'] Hint: Consider the example_function below. It takes a list of numbers in numbers and keeps only those that appear in search_numbers. def example_function(numbers, search_numbers): keep = [] for number in numbers: if number in search_numbers(): keep.append(number) return keep def search_words(data, search_words):arrow_forwardI am very confused on how to answer this and any thing will help. Create a function that accepts a single list. Inside the function, have nested for loops (a for loop inside a for loop). The outer for loop iterates through every item in the list. The inner loop iterates through every subitem in item, and prints it. Test the function by passing it the list [ [0, 1, 2], [3, 4, 5], [6, 7, 8] ].arrow_forwardIN PYTHON PLEASE Write a function def sameSet(a, b) that checks whether two lists have the same ele- ments in some order, ignoring duplicates. For example, the two lists 149 16 9 7 4 9 11 and 11 11 7 9 16 4 1 would be considered identical. You will probably need one or more helper functions.arrow_forward
