Problem J
Pot

The teacher has sent an e-mail to her students with the following task: “Write a program that will determine and output the value of $X$ if given the statement:

\[ X = \mathit{number}_1^{\mathit{pow}_1} + \mathit{number}_2^{\mathit{pow}_2} + \ldots + \mathit{number}_ N^{\mathit{pow}_ N} \]

and it holds that $\mathit{number}_1$, $\mathit{number}_2$ to $\mathit{number}_ N$ are integers, and $\mathit{pow}_1$, $\mathit{pow_2}$ to $\mathit{pow}_ N$ are one-digit integers.” Unfortunately, when the teacher downloaded the task to her computer, the text formatting was lost so the task transformed into a sum of $N$ integers:

\[ X = P_1 + P_2 + \ldots + P_ N \]

For example, without text formatting, the original task in the form of $X = 21^2 + 125^3$ became a task in the form of $X = 212 + 1253$. Help the teacher by writing a program that will, for given $N$ integers from $P_1$ to $P_ N$ determine and output the value of $X$ from the original task.

Input

The first line of input contains the integer $N$ ($1 \leq N \leq 10$), the number of the addends from the task. Each of the following $N$ lines contains the integer $P_ i$ ($10 \leq P_ i \leq 9999$, $i = 1, \ldots , N$) from the task.

Output

The first and only line of output must contain the value of $X$ ($X \leq 1\, 000\, 000\, 000$) from the original task.
