Problem Statement

You are given a sequence of $26$ integers $P=(P_1,P_2, \\ldots ,P_{26})$ consisting of integers from $1$ through $26$. It is guaranteed that all elements in $P$ are distinct.

Print a string $S$ of length $26$ that satisfies the following condition.

• For every $i$ $(1 \\leq i \\leq 26)$, the $i$-th character of $S$ is the lowercase English letter that comes $P_i$-th in alphabetical order.

Constraints

• $1 \\leq P_i \\leq 26$
• $P_i \\neq P_j$ $(i \\neq j)$
• All values in input are integers.

Input

Input is given from Standard Input in the following format:

$P_1$ $P_2$ $\\ldots$ $P_{26}$

Output

Print the string $S$.
