Sum of Two Long Integers
Read two large integers and print their sum using 64-bit arithmetic.
Input format
A single line with two large integers A and B.
Output format
Print the sum A + B. The result can be large, so use a 64-bit integer type (long in Java, long long in C++).
Constraints
- Values fit in a 64-bit signed integer
- Trailing whitespace and a trailing newline are ignored by the judge
Read from stdin, write to stdout. Sample cases below show the exact format.
