Mean before 0
Given a sequence of floating-point numbers, your task is to find out the mean of all the numbers that appear before the first 0 in the sequence.
The input of the program contains a sequence of floating-point numbers. Everything after 0 should be ignored. It’s guaranteed that the input contains at least one number before the first 0.
The program should print a single number - the average of the sequence before 0.
