Write a darken_filter and change_picture function that modifies the pixels in the left half of the image to be darker. You can darken a pixel by subtracting the same value from each of the red, green, and blue values of the pixel.

for every pixel in the left half of the image
set pixel red to be (red - DARKENING_FACTOR)
set pixel green to be (green - DARKENING_FACTOR)
set pixel blue to be (blue - DARKENING_FACTOR)

well cos like a ds it doesn't really die out, unlike for example, fifa, they always come out with a new version, so lets say your fifa 18 is charging you to update the teams and stuff, so, if messi were to go to real madrid (never gonna happen) it would switch messi to the other team, until the owners of fifa come out with fifa 19, then the game would eventually stop updating, and back to the ds, it doesn't really stop working after sometime because there's lots of things that it could be used for, and idk if u know what i'm saying, but long story short, samsung, represents the ds, if they still work, and people love them but not the new version, the old version still works, so they don't really force people to buy new phones, get me?
