Show that !(A&&!B) is equivalent to !A || B in C++
Step by step
Solved in 4 steps with 2 images
- Show that !(A&&!B) is equivalent to !A || B in C++ using while loopAnswer in C++ only Chef loves lucky numbers. Everyone knows that lucky numbers are positive integers whose decimal representation contains only the lucky digits 4 and 7. For example, the numbers 47,744, 4 are lucky and 5, 17,467 are not. Let F(x) equal the number of digits d in the decimal representation of the positive integer x. Chef is only interested in F4(x) and F7(x) functions. For a given positive integer N, he wants to know the total number of distinct pairs (L; R) such that F4(L) + F4(L + 1) + ... + F4(R) equals F7(L) + F7(L + 1) + + F7(R) and 1PLEASE SOLVE THIS IN C++ CODE ONLY! PLEASE READ AND DO THE PROGRAM WITH ACCORDING TO THE CONDITIONS GIVEN. PLEASE ALSO WRITE THE USE OR FUNCTIONS OF EACH CODE USED BY INSERTING ITS USE EVERY LINE USING "//" A palindrome is a string that reads the same from front to back as it does from back to front, e.g., "racecar", "radar", "21012". Write a program that will identify whether a given line of input is a palindrome or not. Your program must also be able to determine the following sample inputs as palindromes, aside from identifying one-word inputs: Able was I 'ere I saw Elba. Madam, I'm Adam. A man, a plan, a canal, Panama. These samples require that your program must ignore spaces and punctuations, and consider uppercase and lowercase letters to be the same. Include necessary functions in your program to process the input. You can also use existing functions from the string library.Answer in C++ Only Ranjit has always been very interested in palindromic strings. So as the word suggest palindromic string is a string which is same form both the end. Recently, he discovered something interesting on palindrome and that made him feel really lucky. He came across something known as Lucky Palindromes. Defines a character unit as a lucky palindrome if it is a palindrome containing a "lucky" character unit as a small series. As usual, he now wants to turn every thread he encounters into a lucky palindrome. As a chef, he is a patient and creative man, so he knows the task of changing any string character with any other character very well and can perform this action many times indefinitely. He wants you to write a program that will help him to turn a given series into a lucky palindrome that uses a small amount of functionality and if a few such palindromes can happen, then take out one very small dictionary. Input: 1 laubcdkey Output luckykcul 8In C++ please, thanks. A prime number is an integer n > 1 whose only positive divisors are 1 and n itself. Write a boolean-valued function that determines whether an integer is a prime number.Computer Engineering In multiplication, assume that leading zeroes are not allowed. Write a program in C++ to help Prima that will find all solutions to this problem for any subset of digits from the set {1,2,3,4,5,6,7,8,9}. The input contains the number of digits that will be used and the second line contains the space separated digits. You have print the output with the total number of unique solutions.Sample Input1:52 3 4 6 8Output:1Note: I want to solve my problem with C programming. In no way can this be done with C ++ programming. Questioin: Hidden Secret Problem! In this problem, you are given two names, you have to find whether one name is hidden into another. The restrictions are: You can change some uppercase letters to lower case and vice versa. You can add/remove spaces freely. You can permute the letters. And if both the names match exactly, then you can say that one name is hidden into another. Input Input starts with an integer T (≤ 100), denoting the number of test cases. Each case starts with two lines. Each line contains a name consists of upper/lower case English letters and spaces. You can assume that the length of any name is between 1 and 100(inclusive). Output For each case, print the case number and Yes if one name is hidden into another. Otherwise print No. Sample Input Output 3 Tom Marvolo Riddle I am Lord Voldemort I am not Harry Potter Hi Pretty Roar to man…I am trying to create a monthly mortgage calculator in C++, but i cannot get the function I am trying to create to work. The output it gives for the monthly payment is 53125 for a 150000 loan at 4.25% for 15 years.Please do in c++ only. Correct answer only else downvoted. arrangement of round and square sections is given. You can change the arrangement by playing out the accompanying activities: shift the bearing of a section from opening to shutting as well as the other way around without changing the type of the section: for example you can change '(' to ')' and ')' to '('; you can change '[' to ']' and ']' to '['. The activity costs 0 burles. change any square section to adjust section having a similar bearing: for example you can change '[' to '(' however not from '(' to '['; likewise, you can change ']' to ')' yet not from ')' to ']'. The activity costs 1 burle. The tasks can be acted in any request quite a few times. You are given a string s of the length n and q questions of the sort "l r" where 1≤l<r≤n. For each substring s[l… r], track down the base expense to pay to make it a right section grouping. It is ensured that the substring s[l… r] has an even length. The inquiries…Please use easy logic with proper indentations and comments for understanding!. Coding should be in C++. 1. Write a recursive function named printStars which receives an int parameter. If the parameter is positive, the function prints the given number of asterisks; otherwise the function does nothing. The function does not return a value. Thus, if the printStars(8) is called, ******** (8 asterisks) will be printed. The function must not use a loop of any kind to accomplish its job. Instead, it gets the job done by (recursively) calling itself.The question should be done in C++, please give explanation and running result. 1. Let’s write a function that compares 2 strings and returns true if they were identical, false otherwise. The signature of this function should be: bool word_diff(std::string word1, std::string word2); For example: std::string str1 = "Hello World";std::string str2 = "hEllO World";std::string str3 = "World";std::string str4 = "Hello World";bool result = word_diff(str1, str2); // Falsebool result = word_diff(str1, str3); // Falsebool result = word_diff(str1, str4); // True 2. Now let’s follow a classical approach to compare the content of 2 files. We should open each file, read their content word by word and compare them until a first mismatch occurs.Let’s implement a function called classical_file_diff that takes 2 arguments each of which is a file name and returns a boolean indicating whether the 2 files are identical or not. The signature of this function should be: bool…here is my c++ problem I'm working on. I have to use recursion to find all possible anagrams of a word. for example Please enter a string for an anagram: artMatching word artMatching word ratMatching word tarPlease enter a string for an anagram: regardlessNo matches found the txt file consists of words from A to Z about 28,000 words need help finishing this problem. but may not use any of C++'s iteration constructs (do, while, for, and goto) or any STLalgorithms #include <iostream>#include <fstream>#include <istream>#include <cstring>using namespace std; const int MAXRESULTS = 20; // Max matches that can be foundconst int MAXDICTWORDS = 30000; // Max words that can be read in int loadWords(istream& dictfile, string dict[]);int recBlends(string word, const string dict[], int size, stringresults[]);void showResults(const string results[], int size);void printPermutations(string prefix, string rest); void loop(string prefix, string rest, int i, int max);…SEE MORE QUESTIONS
