Three numbersa. Write a program that reads three numbers and prints “all the same” if they are allthe same, “all different” if they are all different, and “neither” otherwise.b. Write a program that reads three numbers and prints “increasing” if they are inincreasing order, “decreasing” if they are in decreasing order, and “neither”otherwise. Here, “increasing” means “strictly increasing”, with each value largerthan its predecessor. The sequence 3 4 4 would not be considered increasing.c. Repeat part b. but before reading the numbers, ask the user whetherincreasing/decreasing should be “strict” or “lenient”. In lenient mode, thesequence 3 4 4 is increasing and the sequence 4 4 4 is both increasing anddecreasing
Q1__;. A phrase is a palindrome if, after converting all uppercase letters into lowercase letters and removing all non-alphanumeric characters, it reads the same forward and backward. Alphanumeric characters include letters and numbers. Given a string s, return true if it is a palindrome, or false otherwise. Example 1: Input: s = "A man, a plan, a canal: Panama" Output: true Explanation: "amanaplanacanalpanama" is a palindrome. Example 2: Input: s = "race a car" Output: false Explanation: "raceacar" is not a palindrome..
plz solve it asap ????????: Write a program for a game that consists of two players. The rule of the game is that player 1 inputs a random number from 1-100. Player 2 will input 5 numbers. If the summation of those numbers is equal to the number OR less than or greater than the number by 3 (+3 or -3), then player 2 wins. Otherwise, player 1 wins. Test Case 1 Input Player 1, enter a number: 50 Player 2, enter a number: 10 Player 2, enter a number: 10 Player 2, enter a number: 20 Player 2, enter a number: 5 Player 2, enter a number: 7 Output Player 2 wins Explanation: The summation of 10,10,20,5 and 7 is 52 which is greater than 50 by 2. According to the rule, player 2 wins. Test Case 2 Input Player 1, enter a number: 50 Player 2, enter a number: 10 Player 2, enter a number: 10 Player 2, enter a number: 20 Player 2, enter a number: 5 Player 2, enter a number: 1 Output Player 1 wins Explanation: The summation of 10,10,20,5 and 1 is 46 which is less than 50 and also doesn’t…
In this assignment you will use the MyString class that you wrote earlier in this course. A palindrome is a string that reads the same forward and backward. Write a program that reads in any number of MyStrings from the user and determines if each MyString is a palindrome. The user will terminate each MyString by pressing the return (or enter) button. The user will indicate that there are no more MyStrings by entering "quit". To do this you must write a recursive function named isAPalindrome that takes a single MyString argument and two arguments that are bounds on MyString indices. The function must examine the part of the argument between the two bounds (including the bounds) and return true if this part of the argument is a palindrome, false if it is not a palindrome. The function must be recursive and must not call any other functions except ispunct(), isspace(), and toupper() (described below). Do not make any changes to the MyString class (except, if necessary, to correct errors…
Write a program called palindrome.cpp. The program should have the two functions listed below. Your program should loop until the user enters “quit". The determination of a word being a palindrome or not should be case insensitive. void getWord ( string& word ): This function is responsible for getting the word from the user. void isPalindrome ( string& word, bool& result ): This function is responsible for determining if a word is a palindrome or not. It will return true if the word is a palindrome and false if the word is not a palindrome using a boolean variable passed by reference. Sample Output 1 What is the word? Kayak Kayak is a palindrome Sample Output 2 What is the word? APPLE APPLE is not a palindrome Notes • Remember that you can access each character in a string by using the index operator, i.e., word[3], and the highest index of any string is the length of the string minus one. • To handle the case-insensitivity part you may need to work with functions that change the case…

Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs Yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: Yes Ex: If the input is: 42,000 or 1995! the output is: No Hint: Use a loop and the Character.isDigit() function.
Part a:Finding Pythagorean Triples with OpenMPWrite a program that calculates Pythagorean triples using nested for loops. The Pythagorean Theorem states the following:?2 + ?2 = ?2Where a, b, and c are whole numbers. Part b: Modifying the Pythagorean Theorem Modify the Pythagorean Theorem by either adding or subtracting a times b on the left-hand-side, and run the program again. Are there integer solutions for this??2 + ?2 + ??= ?2
The countSubstring function will take two strings as parameters and will return an integer that is the count of how many times the substring (the second parameter) appears in the first string without overlapping with itself. This method will be case insensitive. For example: countSubstring(“catwoman loves cats”, “cat”) would return 2 countSubstring(“aaa nice”, “aa”) would return 1 because “aa” only appears once without overlapping itself. public static int countSubstring(String s, String x) { if (s.length() == 0 || x.length() == 0) return 1; if (s.length() == 1 || x.length() == 1){ if (s.substring(0,1).equals(x.substring(0,1))){ s.replaceFirst((x), " "); return 1 + countSubstring(s.substring(1), x); } else { return 0 + countSubstring(s.substring(1), x); } } return countSubstring(s.substring(0,1), x) + countSubstring(s.substring(1), x); } public class Main { public static void main(String[] args) { System.out.println(Recursion.countSubstring("catwoman loves cats","cat"));…
Exercise III: Catalan numbers For n e N, denote by c, to be the number of ways to form a "mountain range" with n upstrokes (U) and n downstrokes (D) that all stay above a horizontal line. For instance: for n = 1, only UD is allowed, so c = 1; • for n = 2, only UUDD and UDUD are allowed, so c2 = 2. 1. Check that c3 = 5 by writing down or drawing all possible options. 2. Consider the power series +00 g(x) = 2 n=0 (by definition co = 1) called the generating function of the sequence (en). Justify that cn < 4" for each n, and deduce that the radius of convergence of g is at least 1/4. 3. It can be show that for r E (-1/4, 1/4), g(x) = 1+ xg(r)? and therefore 1- VI 4.x g(x) = 2.x Use this formula and the known power series of V1+ x to write the first terms of the power series expansion of g, in the form g(x) = co + c1x + c2x2 + C3x + c4x* + ·.. Show how you obtain a few terms, but you do not need to show all computations and you can use a calculator for fractions. Check that you recover co,…
Coin Exchange: Write a program that will determine how many coins of each denomination (50kr, 25kr, 10kr, Skr, and 1kr) are required to make up a given amount of change. For example, to make 57kr we could use 1 x 50kr, 1 x 5kr, and 2 x 1kr., It should be obvious that many combinations of coins are possible. For example, in the example above, we could make up 57kr with: (57 x 1kr) or (2 x 25kr and 7 x 1kr). However, your program must use the smallest number of coins (10 points). Example program output: Enter amount: 40 40 Kr = 1 x 25Kr 1х 10Кr 1 x 5Kr
