Question
Hi Asap. Thanks
Write a function called calculateFactorial that takes a positive integer n as input and returns the factorial of n. The factorial of a non-negative integer n is the product of all positive integers less than or equal to n.
Example:
Input: 5
Output: 120
Explanation:
calculateFactorial(5) should return 5 * 4 * 3 * 2 * 1, which equals 120.
Remember, the factorial of 0 is defined to be 1. .

Write a function that takes in the current temperature and a boolean value telling if it is raining and it should return True if Alfonso will wear a jacket and False otherwise. Try solving this problem with a single line of code. def wears_jacket(temp, raining): """ >>> wears_jacket(90, False) False >>> wears_jacket(40, False) True >>> wears_jacket(100, True) True """ *** YOUR CODE HERE *** Note that it should either return True or False based on a single condition, whose truthiness value will also be either True or False. Part 2: Rewrite the above function with a lambda expression.arrow_forward//Write a function that loops through and console.log's the numbers from 1 to 100, except multiples of three, log (without quotes) "VERY GOOD" instead of the number, for the multiples of five, log (without quotes) "SUPER AWESOME".

The function has three integer parameters first , second and third that are positive and have the same number of digits. It returns the number of positions where their digits match. For example, if the function was applied to 17345, 97813 and 17313 it would return 1 because only the 2nd digits match. If parameters have illegal values your function can operate however you choose. For example, a program that uses the function follows. int main() { cout <« digitMatch(168, 567, 767) « endl; // prints 1 cout <« digitMatch(143, 243, 343) « endl; // prints 2 return 0; }arrow_forward
