Solved in 2 steps
- Choose one answer from the following options: Question: Which function would be most useful for determining if a certain word is contained in a string representing a sentence? Answers: a) strcspn b) strchr c) strstr d) strrchr8. Create a function called get_missing_letters that prompts the user fortwo English words, and displays which letters of the alphabet are in neither ofthe two words. Convert each string to a set type in order to solve this.8. Which fo the following correctly descibe the ANSCI C declaration below?char *p = "Hello";char * const q = "Hello";const char *r = "Hello";char const *s = "Hello";A. q can be made to point to another string literal.B. r is an non-constants pointer ot a string literal.C. p is defined as a non-constant pointer to a string literal.D. s is a constant pointer to an non-constant string literal. E. q is a constant pointer to a string literal.
- Which of the following statements correctly define Python dictionaries? Choose all that applies. Dictionaries are mutable. A lookup operation means finding the key of some value v. There can be two or more entries with the same keys in a dictionary. The len function works with dictionaries. Items can be accessed by position in a dictionary. Items are accessed by key.1. What type of strings are accepted following Res? a. (a|b)* b. (ab)* c. (a+b)*b(a+b)* d. aa(a+b)* e. aa(a+b)*bbIn python, wihtout using (replace, find, index) insert_substrings_into_string(s, substrs): This function takes a string s and a string substrs. The substrs string will contain 0 or more comma-separated substrings. The string s will contain text with 0 or more special placeholder character sequences. These placeholder character sequences will always begin with the percent character %, followed by one or more digits. The function will create a new string from the original string s where all the placeholder character sequences in s are replaced by the substrings in the string substrs. The placeholder %0 should be replaced by the first substring in substrs (i.e., everything before the first comma, if such a comma exists). The placeholder %1 should be replaced by the second substring in substrs (i.e., everything between the first and second comma, if such a comma exists), and so on. The new string should then be returned. Note: If a placeholder sequence refers to an invalid index (e.g., %10…
- Edit Distance Suppose you are given two strings, 'President' and 'Provident'. 'Provident" is the source string, which has to be transformed into the target string, i.e., 'President'. Considering you have to find L(9, 9), which of the operations is most appropriate to start with? A. Do Nothing B. Insertion C. Deletion D. ReplacementQUESTION 7 Which one of the following is not a Python's predefined data type? A. Class B. Tuple C. List D. DictionaryProblem 2 (Cipher module)• Create a Python file named cipher_module.py with functions to encode and decodestring inputs using the basic Caesar cipher (see here for more informationhttps://en.wikipedia.org/wiki/Caesar_cipher). This cipher is a basic encryptiontechnique that supports encoding and decoding operations on strings.• The encoding operation replaces each character in a string with another charactersome fixed number (shift) of positions down the ASCII table. The string can beencoded using any characters on the ASCII table and no need to use the circular list(where ‘Z’ is followed by ‘A’) image shown below. Your module must have a functionnamed encode() that takes a string and an integer shift (can be positive or negative)as parameters and returns the encoded string using the shift value. This module must Page 3 of 4also have a second function name decode() that takes an encoded string and aninteger shift as parameters and returns the decoded string. The decoding…
- Q3:IN SML language how would I write a string to integer function that inputs a filename and returns zero if the contents inside the file is blank.1. Write a python function to count the number occurrences all vowels present in a string 2. Write a python function to find common characters presents in two words 3. Write a python function to check the given string is palindrome or not 4. Write a python function to read an IP address from stdin (input from user via keyboard) and check whether it is valid or not. LinkedList Excercise: 1- create a function named insert_after( key, data ), it will search for a key and when found insert the data after Ex: linkedlist A->B->C insert_after(B, W) A->B->W->C 2- create a function named insert_before( key, data ), it will search for a key and when found insert the data before Ex: linkedlist A->B->C insert_before (B, W) A->W->B->C 3- create a function named delete_after it will search for a key and when found it will delete the data after EX: A->B->C delete (B) A->CThe code should be in C++, the hints for this are... 1. To search for a word in a line of text, you may use the find() function thatworks with C++ string objects.2. While implementing the search and replace functionality, you may need to makea temporary copy of the text file.
