In C/C++ programming, it is possible to split string into tokens using the built-in function strtok(...) from the header file : char* strtok(char* str, const char* delimiters); A sequence of calls to this function split str into tokens, which are sequences of contiguous characters separated by any of the characters that are part of delimiters. On a first call, the first character is used as the starting location to scan for tokens. In subsequent calls, the function expects a null pointer and uses the position right after the end of the last token as the new starting location for scanning. char str[] = "Test, This, Code."; char* token; token = strtok(str, ",."); while (token != NULL) { printf("%s\n", token); token = strtok(NULL, "‚."); } Using pipes for inter-process communication, write a C program to implement any valid three commands line pipe entered by the user.

Complete the scramble_text() function that takes a single string parameter text. The function returns a new string consisting of the characters in text scrambled order - every pair of characters have their positions swapped. You can assume that the parameter text will have a length of at least 1. For strings with an odd length, the last character remains unchanged in the scrambled text. Some examples of the function being called are shown below. For example: Test text = "I". print (f"{text} --scramble--> {scramble_text (text)}") text = "Hello" print (f"{text} --scramble--> {scramble_text (text)}") text = "superb" print (f"{text} --scramble--> {scramble_text (text)}") Result I --scramble--> I Hello --scramble--> eHllo superb --scramble--> usepbr
Scrabble Scrabble is a game where players get points by spelling words. Words are scored by adding together the point values of each individual letter. Define a function scrabble_score (word:str) -> int that takes a string word as input and returns the equivalent scrabble score for that word. score = {"a": 1, "c": 3, "f": 4, "i": 1, "1": 1, "o": 1, "r": 1, "u": 1, "t": 1, "x": 8, "z": 10} For example, "b": 3, "h": 4, "n": 1, Your Answer: == 20 assert scrabble_score("quick") assert scrabble_score("code") == 7 1 # Put your answer here 2 Submit "e": 1, "d": 2, "g": 2, "k": 5, "j": 8, "m": 3, "q": 10, "p": 3, "s": 1, "w": 4, "v": 4, "y": 4,

The elements are printed on separate lines. The arguments start and stopare bidirectional iterators. Test your function by printing all the stringsmore than 3 characters long in some vector of strings
Which of the following statements is NOT correct? Group of answer choices C++ language provides a set of C++ class templates to implement common data structures, which is known as Standard Template Library (STL); In STL, a map is used to store a collection of entries that consists of keys and their values. Keys must be unique, and values need not be unique; In STL, a set is used to store a collection of elements and it does not allow duplicates; Both set and map class templates in STL are implemented with arrays.
C++ Implement a standard trie for a set of ASCII strings including a terminating character $ for each word. Create a class that has a constructor that accepts the name of an input file as a parameter (a string), and the class should have an operation that test whether a given string is stored in the trie. The driver should allow user to specify the input data file, output number of words in the trie, and then use a y/n loop to check for a few words. Output yes or no for each search word. You should format your input file's words to lowercase and remove extra characters like comma, periods, etc.
In c++ Please Write the InOrder() function, which receives a vector of integers as a parameter, and returns true if the numbers are sorted (in order from low to high) or false otherwise. The program outputs "In order" if the vector is sorted, or "Not in order" if the vector is not sorted. Ex: If the vector passed to the InOrder() function is [5, 6, 7, 8, 3], then the function returns false and the program outputs: Not in order Ex: If the vector passed to the InOrder() function is [5, 6, #include <iostream>#include <vector>using namespace std; bool InOrder(vector<int> nums) { /* Type your code here */} int main() { vector<int> nums1(5); nums1.at(0) = 5; nums1.at(1) = 6; nums1.at(2) = 7; nums1.at(3) = 8; nums1.at(4) = 3; if (InOrder(nums1)) { cout << "In order" << endl; } else { cout << "Not in order" << endl; } vector<int> nums2(5); nums2.at(0) = 5; nums2.at(1) = 6;…
Using c++ Contact list: Binary Search A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name. Define and call the following function. The return value of FindContact is the index of the contact with the provided contact name. If the name is not found, the function should return -1 This function should use binary search. Modify the algorithm to output the count of how many comparisons using == with the contactName were performed during the search, before it returns the index (or -1). int FindContact(ContactInfo contacts[], int size, string contactName) Ex: If the input is: 3 Frank 867-5309 Joe…
Here is a function that is supposed to return True if word (any string) ends with "s" and False otherwise: def ends_with_s(word):if len(word) < 1:return False return word[-1] == "s" Here is the test function I am using to test ends_with_s: def test_ends_with_s(): assert(ends_with_s("cats")) # option 1 assert(ends_with_s("") is False) # option 2 assert(ends_with_s("apple") is False) # option 3 assert(ends_with_s("S")) # option 4 Rewrite ends_with_s so that the test passes
post in python please and a coding editor too You are asked to help write a program that will help users purchase cookies. A user will input types of cookies and the number of cookies that they want, and your program will suggest how many boxes that they should order. There are 30 cookies per box, so your goal is to make sure that the user will buy enough boxes so that they will get the cookies that they want. Write a function cookie_order that takes a dictionary as a parameter containing cookie names as keys and numbers of those cookies as values. Have this function return a new dictionary that has cookie names and the number of boxes that should be purchased of each type. Hint: This means if someone wants 31 cookies, they need to buy 2 boxes of cookies of that type. You may want to consider using math.ceil for this problem. Examples: >>> cookie_order({'thin mints': 97}) {'thin mints': 4} >>> cookie_order({'thin mints':34, 'shortbread': 60, 'caramel delites': 71,…
In C++ Develop a simple spell checker and word suggestion program using Hashing. A dictionary of words should be given as a first argument (filename) in the program. This input file is the simple text file "Dictionary.txt", where each line is a word (see Files section). The program must ask the user to give a word. (case 1) The program must respond with “True” if the word exists in the dictionary, and must suggest words (from Dictionary) starting with the same first two letters. At the end of each suggestion the exec. time (in micro-sec) must be displayed (see "TimeInterval.h" in Files section). (case 2) If the input word does not exist in Dictionary due to user misspelling, and considering the first letter is correct, the program should return a recommended word from the dictionary (only one word). For example, instead of the word sentence, the user enters snetence, setnence, sentens, or setence, etc; the program should return: "do you mean sentence?" If "no", return "false". If…
In c++, please! Thank you! Write a void function SelectionSortDescendTrace() that takes an integer array and sorts the array into descending order. The function should use nested loops and output the array after each iteration of the outer loop, thus outputting the array N-1 times (where N is the size). Complete main() to read in a list of up to 10 positive integers (ending in -1) and then call the SelectionSortDescendTrace() function. If the input is: 20 10 30 40 -1 then the output is: 40 10 30 20 40 30 10 20 40 30 20 10 The following code is given: #include <iostream> using namespace std; // TODO: Write a void function SelectionSortDescendTrace() that takes// an integer array and the number of elements in the array as arguments,// and sorts the array into descending order.void SelectionSortDescendTrace(int numbers [], int numElements) { } int main() { int input, i = 0; int numElements = 0; int numbers [10]; // TODO: Read in a list of up to 10 positive…
Programming language: Dr. Racket Write a function encode that consumes a string message. The function produces a string which is encrypted according the following procedure: Only the letters from the original message will be encrypted. Other characters such as spaces, punctuation, numeric digits, etc. are not included in the encrypted message at all. The encrypted message will only contain uppercase letters. Each letter will be replaced by the uppercase letter at the opposite end of the English alphabet.In other words, A or a will become Z, B or b will become Y, C or c will become X, ..., Z or z will become A. The encrypted message will have a single space separating each letter. You may assume that the letters in message are English letters only. For example: > (encode "Cat") "X Z G" > (encode "Is this correct?") "R H G S R H X L I I V X G"
