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 p int tlen = strlen(t); // len of string t // TODO: your code Analyze your algorithm: what is the big O?

palindromes Write a function palindromes that accepts a sentence as an argument. The function then returns a list of all words in the sentence that are palindromes, that is they are the same forwards and backwards. Guidelines: • punctuation characters .,;!? should be ignored • the palindrome check should not depend on case Sample usage:>>> palindromes ("Hey Anna, would you prefer to ride in a kayak or a racecar?") ['Anna', 'a', 'kayak', 'a', 'racecar']>>> palindromes ("Able was I ere I saw Elba.") ['I', 'ere', 'I']>>> palindromes ("Otto, go see Tacocat at the Civic Center, their guitar solos are Wow!") ['Otto', 'Tacocat', 'Civic', 'solos', 'wow']>>> palindromes ("Otto, go see Tacocat at the Civic Center, their guitar solos are wow!")==['Otto', 'Tacocat', 'Civic', 'solos', 'wow'] True

vowelIndex Write a function vowelIndex that accepts a word (a str) as an argument and returns the index of the first vowel in the word. If there is no vowel, -1 is returned. For this problem, both upper and lower case vowels count, and 'y' is not considered to be a vowel. Sample usage:>>> vowelIndex('hello') 1>>> vowelIndex('string') 3>>> vowelIndex('string') 3>>> vowelIndex('BUY') 1>>> vowelIndex('APPLE') 0>>> vowelIndex('nymphly') -1>>> vowelIndex('string')==3 True>>> vowel Index ('nymphly')==-1 True

Scala Programming: Given string str, write a Scala program to create a new string where "Scala " is added to the front of a given string. If the string already begins with "Scala", return the string unchanged. Otherwise, return the string after adding "Scala ". Test the function for two strings "Scala Programming" and "Programming" inside the main method.

get_nth_comma_in_string(s, n): This function takes a string s and a non-negative integer n as input. It returns the index of the n’th comma in the string s. We will start counting at 0, so if n=0, then the index of the first comma should be returned; if n=1, then the index of the second comma should be returned, and so on. If there is no n’th comma in s, then -1 should be returned. Note: You may use the string find method in this function.

Python question Analysis: Invariants (Q16-17) For each of the following functions, identify the loop invariant, exit condition and post condition. Question 16 (Invariant 1) This function returns the list of integers that are multiples of both 3 and 7 that occurs within a given list. Identify the loop exit condition, the loop post-condition, and the loop invariant at the end of the loop, which shows the algorithm’s correctness. def multiples_count(lst): """ Input: a list of integers, lst Output: the list of integers in lst that are multiples of both 3 and 7 """ res = [] for i in range(len(lst)): if lst[i]%3 == 0 and lst[i]%7 == 0: res.append(lst[i]) # Identify the loop invariant here return res Question 17 (Invariant 2) This function checks if a given list (of comparable elements) is sorted in ascending order. Identify the loop exit condition, the loop post-condition, and the loop invariant at the end of each iteration of the loop, which...

String orig_string is read from input. Assign variable sliced_string with the orig_string slice that excludes the characters at indices 10 and 11.

5. use c code to Write a stringSearch function that gets two strings one called needle and the other called haystack. It then searches in the Haystack for the needle. If it finds it, it returns the index of where the needle starts in the haystack. If the needle cannot be found, it should return -1 Prototype: int stringSearch(char needle[], char haystack) Example1: Haystack: "This is just an example" Needle: "just" Result: 8 Example2: Haystack: "This is just an example" Needle: "This" Result: 0 Example3: Haystack: "This is just an example" Needle: "this" Result: -1 Hint: all the answer need to include an output and use c code to answer

4. Complete the function show_upper. This function takes one parameter - a string (s). It should return a string made up of all the upper-case characters in s. For example, if s is "aBdDEfgHijK" then show_upper should return "BDEHK". It should return the upper-case string - not print it. Do not change anything outside show_upper.

plase skip it if you dont know the correct answer i need it urgent. Will doewnvote in case of wrong or copied answers from chegg or bartleby! 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 'e'? It should return True otherwise false.
