Can you help her out?Y, E, and S are all composed of images of 7*9 pixels under normal circumstances. However, the actual images may be rotated clockwise by 90°, 180°, or 270°. They may also be stretched horizontally or vertically , or stretched horizontally and vertically at the same time, but the number of pixels in the final enlarged image will not exceed one million. The following images are the normal images of Y, E, and S, as well as three rotated images of Y and three stretched images of E.
