Population Growth Simulation

You are given two integers: the initial population p and the number of hours h. Every hour, the population doubles. Your task is to compute the population after h hours.

The population can be computed using the formula: $$ P = p \times 2^h $$.

Constraints:

• 1 \(\leq\) p \(\leq\) 10⁶
• 0 \(\leq\) h \(\leq\) 100

inputFormat

The input consists of a single line containing two space-separated integers: p and h. Here, p is the initial population (1 (\leq) p (\leq) 10⁶) and h is the number of hours (0 (\leq) h (\leq) 100). The input is to be read from standard input (stdin).

outputFormat

Output a single integer representing the population after h hours, computed as $$ p \times 2^h $$. The output should be printed to standard output (stdout).## sample
