If you erase lower two bits in the red value, you can clear space for hiding values 0–4.
``` for p in getPixels(picture): # Clear out the red 2xLSB r = getRed(p) setRed(p,r-(r%4)) ``` If you erase the lower two bits from red, green, and blue, you can save six bits. Six bits can encode 64 values. That’s enough to encode all 27 letters, both upper and lower case. (a) Write a function to input a picture and a string. Save each character in the string in a pixel of the picture, by saving it across the least significant two bits in each of red, green, and blue. Can you tell the difference between the original picture and the picture with the encoded text message? No, it’s highly unlikely someone could tell a difference between the original and the modified picture. Note: The below method special cases for the space character, as otherwise messages cannot include spaces, this is possible to do as six bits allows for additional space beyond the 54 needed for upper and lower case letters. (b) Now write a function to decode the original text.
