Description

Xiao A is active on various platforms, and people often refer to him by his follower count on each platform.

Specifically, take the first letter of the website name (preserving its case) and concatenate it with the follower count to form the corresponding alias. For example, if Xiao A has $20$ followers on Bilibili, the alias is B20; if he has $0$ followers on wikidot, the alias is w0.

Given the website name and follower count, output the corresponding alias.

Input Format

The first line contains a string representing the website name.

The second line contains a non-negative integer representing the follower count.

Hint

For $30\%$ of the data, the website name is guaranteed to be bilibili.

For all data, the website name is a string of length at most $20$ containing only English letters, and the follower count is a non-negative integer not exceeding $10^7$.
