- In python when you work with text, sometimes you need to determine if a given string starts with or ends with certain characters. string methods to solve this problem: .startswith() and .endswith()?The number of permutations of a set of n items taken r at a time is given by the followingformulan!/r!(n−r)!: where n! is the factorial of n, r! is the factorial of r, and (n-r)! is thefactorial of the result of n-r. The factorial of a number n can be solved using the followingformula: n!=e−nnn√ 2πn.If there are 18 people in your class and you want to divide the class into programming teams of 3members, you can compute the number of different teams that can be arranged using this formula(n!/r!(n−r)!).Write a C++ program that determines the number of potential team arrangements. You will needto use the double type for this computation. Use the Lab Template you set-up last week, properformatting, and appropriate comments in your code. The output must be labeled clearly andformatted neatly.The weather generator methods you will be writing for this assignment will: predict future precipitation pattern for one month: oneMonthGenerator find the number of wet or dry days in a given month’s forecast: numberOfWetDryDays find the longest wet or dry spell in a given month’s forecast: lengthOfLongestWetDrySpell

Compare the user's answer and the random secret letter generated;5). If the user answer is before the random secret letter in the alphabet, display "Incorrect. Trysomething later in the alphabet" and go to Step 2;6). If the user answer is after the random secret letter in the alphabet, display "Incorrect. Trysomething earlier in the alphabet." and go to Step 2;7). If the user answer is the same as the random secret letter, display "Well done. Want to playagain (y/n)?";8). Read the user's answer.

- What happens if you try to multiply a string by a string, "a" * "b"?Write 3 ways in java to find the string length without using length method. I am asking without length method where you can use length keyword.please code this alsoIdiot’s Delight is a fairly simple game of solitaire, yet it is difficult to win. The goal is to draw all of the cards from the deck, and end up with no cards left in your hand. You will run through the deck of cards one time. Start by dealing 4 cards to your hand. You will always look at the last 4 cards in your hand. If the ranks of the “outer” pair (1st and 4th) are the same, discard all four cards. Otherwise, if the suits of the “inner” pair (2nd and 3rd) are the same, discard those 2 cards only. If you have less than 4 cards, draw enough to have 4 cards in your hand. If the deck is empty, the game is over. Your score will be the number of cards that remain in your hand. Like in golf, the lower the score the better. Create a new Python module in a file named “idiots_delight.py”. Add a function called deal_hand that creates a standard deck of cards, deals out a single hand of 4 cards and returns both the hand and the deck. Remember that for the last assignment, you created several…
