- 1. Write a program that reads a number between 1,000 and 999,999 from the user, where the user enters a comma in the input. Then print the number without a comma. Here is a sample dialog; the user input is in color: Please enter an integer between 1,000 and 999,999: 23,456 23456 Hint: Read the input as a string. Measure the length of the string. Suppose it contains n characters. Then extract substrings consisting of the first n - 4 characters and the last three characters. 2. Writing large letters. A large letter H can be produced like this: * It can be declared as a string literal like this: final string LETTER_H = "* *%n* *n*****n* *n* *%n"; Print the string with System.out.printf. The en format specifiers cause line breaks in the output. Do the same for the letters E, L, and O. Then write in large letters: O 3. Write a program that transforms numbers 1, 2, 3,..., 12 into the corresponding month names January, February, March, ..., December. Hint: Make a very long string "January…A cryptogram is a coded message using alphabet substitution. For example, the letter "A" in the cryptogram might stand for the letter “Ż." You are to write a program that allows the program user to decipher cryptograms, like the following one. Your program should allow the user to change one letter and display the change, then change another letter and display the change etc. Here is a sample cryptogram to be decoded. String crypto.Part1 = "EKBQUDUHJ XK BCA AYGADDAMB KGENAHUEB UP" String crypto.Part2 = "BCA ZUQDR FDEIA BCA KBEWQK PUG UOQ PEODBK." String crypto.Part3 = "CUZALAQ PQXAMRK UOQ EODBK DXA MUB IM BCA" String crypto.Part4 = "KBEQK FOB XM UOQKADLAK."Write a program that generates the positions of whitespaces in a string and prints them on the screen. For example given the following string as input: "hello there my friends" the program should generate: 5, 11, 14
- Write a program that reads a string and checks the longest substring starting with "a" and ending with "z" included in it. Note that, the substring cannot contain another a or another z in it. For example: Ifs="bcd bbccdd badefgze tabdz", the longest substring is: 6Write a program which reads string and rewrite it in alphabetical order. For example, the word STRING should be written as GINRST.Q_4.*. 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..
- Using Javascript and HTML: An interesting application of computers is drawing graphs and bar charts (sometimes called histograms). Write a script that reads five numbers between 1 and 30. For each number read, output HTML5 text that displays a line containing the same number of adjacent asterisks. For example, if your program reads the number 5, it should out HTML5 test that displays *****.Write a program that reads a sentence and store it in an array of characters. The program also reads a word and store in it a string variable. The program then conceals the word in the sentence with the character @'. Sample input / output: Enter a sentence: The town in which we live is a green town and big Enter a word: town Result: The @aa@ in which we live is a green @@@@ _and bigA palindrome is a word or phrase that reads the same forward and backward, ignoring blanks and considering uppercase and lowercase versions of the same letter to be equal. For example, the following are palindromes:warts n strawradarAble was I ere I saw Elbaxyzczyx Write a program that will accept a sequence of characters terminated by a period and will decide whether the string—without the period—is a palindrome. You may assume that the input contains only letters and blanks and is at most 80 characters long. Include a loop that allows the user to check additional strings until she or he requests that the program end. Hint: Define a static method called is Palindrome that begins as follows: /** Precondition: The array a contains letters and blanks in positions a[0] through a[used − 1]. Returns true if the string is a palindrome and false otherwise. */ public static boolean is a palindrome(char[] a int used) Your program should read the input characters into an array whose base…
- 3. Write a program that transforms numbers 1, 2, 3,..., 12 into the corresponding month names January, February, March, ..., December. Hint: Make a very long string "January February March ...", in which you add spaces such that each month name has the same length. Then use substring to extract the month you want.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());You have to construct a string “cmpmpcmpm” from a blank string. There are two ways to construct a string.1. Operation 1: You can add any character at the end of the string. It will cost you 5 points.2. Operation 2: You can copy any substring of string at the end of the string. It will cost you 6 points.The operations that you will choose to construct the string with minimum cost are:
