b).

3.a. if x is larger than y, x equals temperature, equals y, and y equals temperature too.
if x is less than or equal to y, then y equals temperature, equals x, and x equals temperature.
b. when sum equals one, and count equals 1, put an integer to the total.
But when count is less than or equal to total, make x into an integer. Sum equals sum added by absolut value of x. total is greater than 0, sum divided by total.
