CODE MUST BE WRITTEN IN SWIFT programming language Write a function that takes in two positive integers and prints every prime number between (and including) them Sample Input: prime(from: 0, to: 100) Sample Output: [2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97]
USE PYTHON PLEASE Write a function called is prime which takes a single integer argument and returns a single Boolean value representing whether the given argument is prime (True) or not (False). After writing the function, test it by using a loop to print out all the prime numbers from 1-100. To check your results, the prime numbers from 1-100 are: 2, 3, 5, 7, 11. 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67,...
I need it in JAVA Write a program that randomly populates an array of size 100, sorts it, and then finds the median. The random numbers must be from 0-99 and all integer values. Also since there is an even set of numbers the median is found by taking the mean of the two middle numbers (In other words the 50th and 51st). You have to code your own sorting method. You may not use a built in java sorter....
