Problem Write a program that captures input from the user. Then, swap the letters two at a time in the string. The first two characters change places, the third and fourth characters change places, etc. Assume that the user will only input strings with an even number of characters.

Write a program that reads a character and a string (an entire line, which may include spaces or tabs), and outputs the number of times the character appears in the string. Hint: use getline(cin, mystring) to read the entire line including spaces. Use mystring.length() to know how many characters. But to avoid a glitch when getline gets an empty string following a cin, do the following sequence: cin >> mychar; /* get character. cin leaves the newline in the input buffer*/ cin.ignore(80,'\n'); /* remove newline from the buffer, which getline would see as empty line*/ cout << "Enter a string: "; //prompt for string getline(cin, mystring); Example program run (the user types only the word "Monday" and the letter "a"): Enter character to count: a Enter a string: Monday count = 1 Example program run: Enter character to count: a Enter a string: Today is Monday count = 2 Example program run: Enter character to count: b Enter a string: Today is Monday count = 0 #include…
write a program that allows the input of a string from the user and prints the longest word in that string and its length. If there are multiple words with the same maximum length you must print the first one only.
Two words are anagrams if they contain all of the same letters, but in a different order. For example, “evil” and “live” are anagrams because each containsone ‘e’, one ‘i’, one ‘l’, and one ‘v’. Create a program in python that reads two strings from the user, determines whether or not they are anagrams.
I need to write a palindrome Java program. Given a string of letters, it should find the minimum number of letters that need to be removed from the string, so that a reordering of the letters will result in a palindrome (a word that reads the same backwards as it does forwards. Such as racecar or tacocat. The given sample while loop for this is final Scanner stdin = new Scanner(System.in, "US-ASCII"); while (stdin.hasNext()) { final String s = stdin.next(); } A sample input is in the attached picture
Read the input one line at a time and output the current line if and only if it is largerthan any other line read so far or strictly smaller than the previously outputted line. (Here,smaller is with respect to the usual order on Strings, as defined by String.compareTo()). you have to use arrylist and cant modify any code under public static void main(string[] args). example: input 138456792 output: 138492 import java.util.*; import java.io.BufferedReader; import java.io.FileReader; import java.io.FileWriter; import java.io.IOException; import java.io.InputStreamReader; import java.io.PrintWriter; import java.util.Stack; public class Part2 { /** * Your code goes here - see Part0 for an example * @param r the reader to read from * @param w the writer to write to * @throws IOException */ public static void doIt(BufferedReader r, PrintWriter w) throws IOException { /*ArrayList<String> arr = new ArrayList<>(); int count…
Write a program that takes a string as input and outputs the string in all capital letters and the length of the string. The output should follow the format from the example below. Example:Enter a DNA strand: aAtcDNA strand: AATCLength: 4Tip: make use of the .upper() method, the len() function, and the ‘\t’ escape character to add tabs.
given the strings s1 and s2, not necessarily of the same lenght, create a new string consisting of alternating characters of s1 and s2 (that is, the first character of s1 followed by the first character of s2, followed by the second characters of s1, followed by the second character of s2, and so on. Once the end of either string is reached, the reminder of the longer string is added to the end of the new string. For example, if s1 contained "abc" and s2 contained"uvqxyz", then the new string should contain "aubvcwxyz". Assign the new string to the variable s3. using python and loops
def loopy_madness_with_while_loops(string1: str, string2: str) -> str:"""Given two strings <string1> and <string2>, return a new string thatcontains letters from these two strings "interwoven" together, starting withthe first character of <string1>. If the two strings are not of equallength, then start looping "backwards-and-forwards" in the shorter stringuntil you come to the end of the longer string."interwoven" (or "interweaving") means constructing a new string by takingthe first letter from the first string, adding the first letter of thesecond string, adding the second letter of the first string,adding the second letter of the second string, and so on."backwards-and-forwards" is a custom looping term. First the loop startsat position 1 (index 0) and goes until position n (i.e., the end). Once theloop reaches position n, it goes backwards, starting at position n - 1 andgoes to position 1 (index 0). This repeats until the two strings areinterwoven. For example,…

Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, and output all integers less than or equal to that value. Ex: If the input is:05506014020075100 the output is:506075 The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75. Such functionality is common on sites like Amazon, where a user can filter results. Your code must define and call the following two functions: def get_user_values()def output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold) Utilizing functions will help to make your main very clean and intuitive.
A finite sequence of symbols from a given alphabet will be called a string over the alphabet. A string that consists of a sequence a1, a2, a3, a4, … … … … , ?? of symbols will be denoted by the juxtaposition a1 a2 a3 a4 … … … … ??. Given the strings: ? = a2bab2and v = bab2, Evaluate the following operations for strings: (i) ԑu(ii) u + v(iii) u(u| v)(iv) v | (v | u)
A palindromic number is a positive integer that reads the same forward as backward. For example, the numbers 1, 11, and 121 are palindromic. Moreover, 1 and 11 are very special palindromic numbers: their squares are also palindromic. How many positive integers less than 10,000 have this property, Palindromic? Write a program to list all such numbers together with their squares. The beginning part of your output should look like this: 1 has square 1 2 has square 4 3 has square 9 11 has square 121 22 has square 484.... ...... Hint: If str is a string object, the reverse() function (declared in <algorithm> header will reverse the string. The code to do that is: reverse(str.begin(), str.end());
