Sum of Two
Easy · rating 800 · math, implementation
Read two space-separated integers a and b on a single line. Print their sum.
Constraints: -109 ≤ a, b ≤ 109
Editorial
Sum of Two is the simplest warm-up: read two integers and print their sum. The one gotcha is range — two values near 10⁹ sum past 32-bit limits, so use a 64-bit integer type (Python and JavaScript widen automatically).
a, b = map(int, input().split())
print(a + b)Complexity
Time: O(1). Space: O(1).
