3. Which among the following shows a valid use of the Direction enumeration as a parameter to the moveCharacter function? Select al that apply. enum Direction {  case north, south, west, east}func moveCharacter(x: Int, y: Int, facing: Direction) {// code here}   moveCharacter(x: 0, y: 0, facing: .southwest)   moveCharacter(x: 0, y: 0, facing: Direction.north)   moveCharacter(x: 0, y: 0, facing: .south)   moveCharacter(x: 0, y: 0, facing: Direction.northeast)

Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'

can ya please do it step by step?   Create a shiny app in R to demonstrate the sampling distribution of sample proportion. Your app shouldaccept following arguments.• Population Proportion• Sample Size• Number of samples: default value is 500Your function should output the sampling distribution of sample proportion as a histogram,mean of sample proportions, and SD of sample proportions.
