Follow these instructions.

1. Develop a CUDA program that rotates the Tucan image we used for the fade example. Here's the tucan image. Here some files to help you.

• The tucan image: Untitled.ppm
• The fade example from the lecture notes: fade.cu, fade_cpu.c
• The helper functions to read, allocate, and write ppm files: ppm.c, ppm.h.

1. Develop a CUDA program that takes two PPM images and merges them. That is every new pixel is the sum of average of the two corresponding pixels from the input images: new[i][j] = (in_a[i][j] + in_b[i][j]) / 2.
