- PHP ATM machines allow 4 or 6 digit PIN codes and PIN codes cannot contain anything but exactly 4 digits or exactly 6 digits. *With user input ($pinNumbers), create a function that takes a string and returns true if the PIN is valid and false if it's not. Examples validatePIN("$1234") ➞ true validatePIN("12345") ➞ false validatePIN("a234") ➞ false validatePIN("") ➞ false Notes ● Some test cases contain special characters. ● Empty strings must return false.Make a function is_palindrome that takes a string as an argument that returns True if the given string is a palindrome, and False otherwise. A string is a palindrome if it is the same if you reverse it. For example: "racecar" "kаyak" "otto" "redivider" "wontloversrevoltnow"The following functions are all intended to check whether a string representing a dna sequence contains any characters that are not 'a','c','g','t', 'A', 'C', 'G', or 'T'. At least some of these functions are wrong. Which ones are correct? A) def valid_dna1(dna): for c in dna: if c in 'acgtACGT': return True else: return False B) def valid_dna3(dna): for c in dna: flag = c in 'acgtACGT' return flag C) def valid_dna4(dna): for c in dna: if not c in 'acgtACGT': return False return True -------------------------------------------------------------------------------------------------------------------------------------------------------- valid_dna1 only valid_dna4 only None of them. valid_dna1, and valid_dna4 only
- 1. A prime number is a number that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6.Write a Boolean function named is_prime which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Use the function in a program that prompts the user to enter a number then displays a message indicating whether the number is prime.Tip:Recall that the % operator divides one number by another and returns the remainder of the division. In an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num2.5. A prime number is a number that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, how- ever, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a Boolean function named is_prime which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Use the function in a program that prompts the user to enter a number then displays a message indicating whether the number is prime. 6. In another program, use the function you wrote in question 5 to print the prime numbers between 1 and 100 using for loop.Part 2: Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is 1995, the output is: yes Ex: If the input is 42,000 or 1995!, the output is: no Hint: Use a loop and the isdigit() function (don't forget to include the cctype library). Do not use break! please do it in c++
- Your program will prompt the user for the following information: current population number of yearly births from the previous year number of yearly deaths from the previous year number of years into the future for your predictive value of the future population. You will then compute the following: birth rate death rate growth rate the predicted future population Assignment Notes: To allow the user to input the numeric data (such as current population) it is necessary to use the input function. The input function takes a string in parenthesis that prompts the user what to enter. The computer then waits until the user types a response, terminated by the user typing the Enter key. A string, as a sequence of characters, is returned to the variable on the lefthand side of the assignment statement. For example: currPopulation = input(“Enter the current US population”) The data in currPopulation is a string (because that is what the input statement does) but we need it to be a number…Write a function void printTriangle(char* str)that gets a string from the user up to length 20 and prints in in the following triangle format If the user enters “Hello” the code should printH HeHelHellHelloCreate a function that accepts a string (of a person's first and last name) and returns a string with the first and last name swapped. Examples NameShuffle("Donald Trump") - "Trump Donald" NameShuffle ("Rosie O'Donnell") - "O'Donnell Rosie" NameShuffle ("Seymour Butts") - "Butts Seymour" • There will be exactly one space between the first and last name. In c#
- In Python Text-based adventure game: Pretend you are creating a text-based adventure game. At different points in the game, you want the user to select to fight, run, or hide from certain enemies. The selection variable must be sent as an argument into the choice() function. The user should enter 1 to fight, 2 to run, or 3 to hide in the main(). The choice() function should print one of the three options. Add an if statement in the choice() function to make the correct selection.Create a function that takes a number (int) and returns a corresponding string of dashes. Examples: num_to_dashes(1) ➞ "-" num_to_dashes(5) ➞ "-----" num_to_dashes(3) ➞ "---"Write the pseudocode for a function that should accept a test score as an argument and return a letter grade for the score (as a String), based on the following grading scale: Score Letter Grade90-100 A80 - 89 B70 - 79 C60 - 69 DBelow 60 F
