Problem Statement
A list of integers is provided. Add numbers one by one until you see 0. Do not include 0 in sum. Output the sum.
Input Format
• First line: Space-separated integers
Output Format
• Print one integer: sum of numbers until 0 appears
• Do not include 0 in the sum
• Do not include 0 in the sum
Example
5 8 3 0 7 9
16
Constraints
• List size ≤ 10^5
• -10^9 ≤ numbers ≤ 10^9
• It is guaranteed that 0 will appear at least once
• -10^9 ≤ numbers ≤ 10^9
• It is guaranteed that 0 will appear at least once
Concept Explanation
We add numbers until we see 0.
5 + 8 + 3 = 16
Stop when 0 appears.
Do not include 0 in sum.
5 + 8 + 3 = 16
Stop when 0 appears.
Do not include 0 in sum.
Step-by-Step Explanation
1.Read the list of integers.
2.Initialize total = 0.
3.Loop through each number in the list:
• If number is 0, break the loop.
• Otherwise, add it to total.
4.Print total.
2.Initialize total = 0.
3.Loop through each number in the list:
• If number is 0, break the loop.
• Otherwise, add it to total.
4.Print total.
