The dictionary snowfall maps keys (which represent a given month) to values that represent the amount of snowfall (in inches) for every time it snowed that month. Write code that creates a new dictionary named month_total_snowfall where the keys are months and the values are floats that represent the total snowfall for that month (the sum of the values in snowfall for that month).

Then, create a new float called snowfall_all_months whoes value is the total snowfall for all months.

snowfalls = {
'December': [0.2],
'January': [1.5, 3, 2, 2.5],
'February': [7, 2.3, 1.2, 4],
'March': [1.5, 3, 4],
'April': [0.2],
}

Me with this program in c++ ! computers represent color by combining sub-colors red, green, and blue (rgb). each sub-color's value can range from 0 to 255. thus (255, 0, 0) is bright red. (130, 0, 130) is a medium purple. (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (in other word, equal amounts of red, green, blue yield gray).given values for red, green, and blue, remove the gray part. ex: if the input is 130 50 130, the output is: 80 0 80. thus, find the smallest value, and then subtract it from all three values, thus removing the gray.
