Record Code

Version: Phuoc Hung OJ Extended

Problem Statement

A record code consists of text prefix $s$, a hyphen -, and a nonnegative serial number $n$. The number must occupy at least four decimal digits. Pad it on the left with zero digits if necessary.

The width of four is a minimum: if $n$ has four or more digits, preserve all digits.

Input

The first line contains prefix $s$. The second line contains nonnegative integer $n$.

Output

Print the record code: prefix, hyphen, then the padded number, with no inserted spaces.

Subtasks

• Subtask 1 (100 points): $1\le |s|\le20$; $0\le n\le10^6$; $s$ consists only of ASCII letters.

Examples

Example 1

Input

TS
7

Output

TS-0007

Explanation. Pad $7$ with three zeros to get 0007, then prepend TS-.

Example 2

Input

A
1234

Output

A-1234

Explanation. $1234$ already occupies four digits, so the result is A-1234.

Example 3

Input

ID
10000

Output

ID-10000

Explanation. $10000$ occupies five digits and is not truncated: ID-10000.
