Product of Two Non-negative Integers

Given two non-negative integers \(a\) and \(b\), compute their product \(a \times b\). This problem tests basic arithmetic operations and input/output handling. Ensure that your solution handles large numbers appropriately if necessary.

inputFormat

The input consists of a single line containing two non-negative integers separated by whitespace. Formally, the input line is:

\(a\) \(b\)

where \(0 \leq a, b \leq 10^{18}\) (if larger values are possible, use appropriate data types).

outputFormat

Output a single integer which is the product of the two given integers.
