Write a C# Sharp program to print on screen the output of a given non-empty string, write a method that returns it in a compressed format. Expected input and output CompressString("CCCCCSSSSSHHHHHAAAAARRRRRPPPPP") → "C5S5H5A5R5P5"

Using sys module in Python. Create a program, longest.py, that has a function that takes one string argument and prints a sentence indicating the longest word in that string. If there is more than one word print only the first. Your print statement should read: The longest word is x Where x = the longest word. The word (x) should be all lowercase.

Write a program that creates an input function to enter a string. Then use .isalpha method to find ifthe first character in the string starts with a letter or a non-letter. (Hint: use indexing and if and if notfunction). Make sure to print the two statements ‘Your string starts with a letter’ and ‘Your stringcontains a non-letter’)

For 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.…
