Question

python

Start with my solution to the rotateLeft function. Modify it to rotate right 90 degrees, instead.

def rotateLeft(oldPic):

  w = oldPic.getWidth()

  h = oldPic.getHeight()

  newPic = Picture(h, w)

  for x in range(w):

    for y in range(h):

      oldColor = oldPic.getColor(x, y)

      newX = y

      newY = w - x - 1

      newPic.setColor(newX, newY, oldColor)

  return newPic

Answer 1

RAW CODE

def rotateRight(oldPic):
    w = oldPic.getWidth()
    h = oldPic.getHeight()
    newPic = Picture(h, w)
    for x in range(w):
        for y in range(h):
            oldColor = oldPic.getColor(x, y)
            newX =  h - y - 1 ### NEW INDEX FOR X
            newY = x ### NEW INDEX FOR Y
            newPic.setColor(newX, newY, oldColor)
    return newPic
