Sum of negatives
Given a stream of numbers, your task is to calculate the sum up until the first non-negative number. All the numbers after the first non-negative one should be ignored.
It’s guaranteed that the input contains at least a single non-negative number. If the first number is non-negative, the program should print 0.
The program should print the required sum.
Input | Output |
-20
-3
-2
-30
0
-1 | -55 |
Explanation: The first non-negative number in the list
-20, -3, -2, -30, 0, -1 is 0. So, we should calculate the sum of numbers before 0. This results in -20 -3 -2 -30 = -55.Constraints
