题目描述
Innokentiy decides to change the password in the social net "Contact!", but he is too lazy to invent a new password by himself. That is why he needs your help.
Innokentiy decides that new password should satisfy the following conditions:
- the length of the password must be equal to $n$ ,
- the password should consist only of lowercase Latin letters,
- the number of distinct symbols in the password must be equal to $k$ ,
- any two consecutive symbols in the password must be distinct.
Your task is to help Innokentiy and to invent a new password which will satisfy all given conditions.

输入格式
The first line contains two positive integers $n$ and $k$ ( $2<=n<=100$ , $2<=k<=min(n,26)$ ) — the length of the password and the number of distinct symbols in it.
Pay attention that a desired new password always exists.

In the first test there is one of the appropriate new passwords — java, because its length is equal to $4$ and $3$ distinct lowercase letters a, j and v are used in it.
In the second test there is one of the appropriate new passwords — python, because its length is equal to $6$ and it consists of $6$ distinct lowercase letters.
In the third test there is one of the appropriate new passwords — phphp, because its length is equal to $5$ and $2$ distinct lowercase letters p and h are used in it.
Pay attention the condition that no two identical symbols are consecutive is correct for all appropriate passwords in tests.
