- Write a program that prompts the user to enter a string and displaysthe characters at even positions. Here is a sample run: Enter a string: Beijing ChicagoejnhcgWrite a program that read text from user and remove all the character from the it except alphabets,space, comma and full stop. The resultant text is to be save to another string and then output thecopied string. For this you need to use a procedure that takes offset of the input string as parameterand then performed the required task on it. Sample Example:Her#e is gr8 0ppurnity!! To 8ec$ome 5ilen7 to 8etter 3ither or n0t @t.Her e is gr ppurnity to ec ome ilen to etter ither or n t t.Write a program that prompts the user to enter a string anddisplaysthe string in reverse order. Enter a string: ABCD ↵EnterThe reversed string is DCBA
- Use Java Programming; You are tasked to make a program that accepts a string. From that string, print out the number of permutations and all the permutations of that string including itself. Expected output: String: abc All permutations of abc: 6 abc acb bac bca cab cbaWrite a program that takes a string and creates a new string made of first two characters and last two characters from the given stringWrite an application that reads a five-letter word from the user and produces every possible three-letter string that can be derived from the letters of that word. For example, the three-letter words produced from the word “bathe” include “ate,” “bat,” “bet,” “tab,” “hat,” “the” and “tea.”
- Write a program that reads the user's first name and last name, and then use them to create a UPM email for the user. If the total number of characters in the user's full name, (first name + last name), is less than 10 letters, you should use the full name to create the user’s email. The general format of the user’s email should look like this: firstName.lastName@upm.edu.sa For example: First name = Ali Last name = Omar Total number of letters in both first and last names = 7 letters (<10 letters) Output = omar.ali@upm.edu.sa If the number of characters in the user's full name, (first name + last name), is greater than or equal to 10 letters, you should only use the first character in the user’s first name, and the whole last name to create an email. For example: First name = Abdullah Last name = Omar Total number of letters in both first and last names = 12 letters (>=10 letters) Output = a.omar@upm.edu.sa Note: you can assume the user will always enter lowercase lettersFor this project, you will be writing regular expressions that look for and find all instances of a date in any given string. Your program should: Find the following different formats for dates: August 2nd, 1994 august 2, 1994 08/02/1994 08/02/94 08-02-1994 Your program should be case insensitive using re.IGNORECASE Your program can only have a maximum of two different regexes. A special prize goes to those of you who can fit all of this into one regex Your program should be able to tell if the date is a valid date. For example, if the date says 99/99/99, then your program should ignore this as a date. HINT: this is not done within the regex. Try saving your dates to something like a list and going through that list after your regex runs. At the end of your program, it should print out all of the dates in the following format: mm/dd/yyyy. EX. 08/02/1994 Your program should use at least two character classes, you may need more. Feel free to make your own custom classes as well.…Write a program that asks the user to enter a word that contains the letter a. The programshould then print the following two lines: On the first line should be the part of the string upto and including the first a, and on the second line should be the rest of the string. Sampleoutput is shown below:Enter a word: buffalobuffalo
- write a program that inserts parentheses, a space, and a dash into a string of 10 user-entered numbers to format it as a phone number. for example 5555555555 becomes (555) 555-5555. If the user does not enter exactly 10 digits, display an error message. continue to accept user input until the user enters 999 using string builder.In Python Write a program that reads a string from the user containing a date in the form mm/dd/yyy. it should print the date in the format March 12, 2018.Write a program that asks the user to enter a string, and then converts that string to Morse code. Use hyphens for dashes and periods for dots. Morse Code Table Character Code Character Code Character Code Character Code space space 6 - . . . . G --. Q --.- comma --..-- 7 -- . . . H . . . .
