LAB RESTRICTIONS, PLEASE READ:Do not add any imports, the ones that you need will be given to you.You may not use any lists or list methods, or any while loops.Within your loops, you MUST NOT use any break or continue statements.Please also do not use try-except statements, you should be able to anticipateor prevent any errors from happening at all! Edef sum string(string: str) -> int:Given a string , return the sum of this string, as computed by theformula given below:To compute the sum of a string as defined by this function, we add everyodd positioned digit, and subtract every even positioned digit. For example,if we had an input of "54321", we would add 5, subtract 4, add 3, subtract2, and add 1, bringing us to a total of 3. In other words, you would add thefirst digit, subtract the second digit, and keep alternating until you reachthe end of the string. If the string is empty, then the sum is 0.Note: since we give the input as a string, you will have to do some typeconversion in order to solve this problem.Precondition: will only contain the characters 0-9.pass

ALGORITHM:- 1. Traverse the string. 2. For each even index add the number. 3. For each odd index…

I have given you the linear search code example on the video and I want you to go through the code and adjust the code. In the following code, list consists of number 4 twice however when you execute this code you find only the first 4.

Problem: Substring Pattern Matching Input: A text string t and a pattern string p Output: Does t contain the pattern p as a substring, and if so, where? For example: with t= abaababbaba, p = abba, your function should return 5. int findmatch(char *p, char *t) { int plen = strlen(p); // len of string int tlen = strlen(t); // len of string t //TODO: your code } Analyze your algorithm: what is the big O?

2. count_fred_and_ted Given a list of strings called names , count up how many of those names are either "fred" or "ted", and return the count. Sample calls should look like: >>> count_fred_and_ted(["sarah", "bimmy", "fred", "eliza", "ted", "ted"]) 3 >> count_fred_and_ted(["sarah", "bimmy", "bimmy", "bimmy", "bimmy"]) >>> count_fred_and_ted(["fred", "ted", "fred", "ted"]) 4 >>> count_fred_and_ted([])
Up for the count def counting_series (n): The Champernowme word 1234567891011121314151617181920212223., also known as the counting series, is an infinitely long string of digits made up of all positive integers written out in ascending order without any separators. This function should return the digit at position n of the Champernowne word. Position counting again starts from zero for us budding computer scientists. Of course, the automated tester will throw at your function values of n huge enough that those who construct the Champernowne word as an explicit string will run out of both time and space long before receiving the answer. Instead, note how the fractal structure of this infinite sequence starts with 9 single-digit numbers, followed by 90 two-digit numbers, followed by 900 three-digit numbers, and so on. This observation gifts you a pair of seven league boots that allow their wearer skip prefixes of this series in exponential leaps and bounds, instead of having to crawl…
Write (i) declares a string (of size [5] 6. a program that str_a (LAST_FOUR_DIGITS_OF_YOUR_STUDENT_ID % 11 + 30)) and initializes with "Your own name, Your own student id". (ii) Take input from user into str_a. This string may have alphabets and digits. (iii) Store only the numerical characters of str_a into another string str_b. (iv) If the string str_b doesn't contain any numerical character, print 0 (zero), otherwise, print str_b. Some example input/outputs are given below: Example 1 Example 2 Example 3 Example 4 abc 123abc 12ab34 Input Output 123 123 123 1234

A regular expression (shortened as regex or regexp; also referred to as rational expression) is a sequence of characters that specifies a search pattern. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings, or for input validation. using regex create a python program to verify the string having each word start from 'p'? It should return True otherwise false.
