PROGRAMMING:Yu Longjian
###Task description
Teacher Yu thought that the addition of Yu Long was not exciting enough, so he designed Yu Long subtraction.
The meaning of subtracting "A-B" by Yu Long of two non negative integers is: in all the numbers of a, all the numbers appearing in B are crossed out, and the remaining number in a is the result, if not, the result is 0.
Yu Long wants to program to solve the problem of long minus. Can he succeed?
###Input format:
Two non negative integers a and B separated by spaces. A can be up to 5 digits, B can be up to 3 digits.
###Output format:
An integer.
###Input example:
```in
12346 24
```
###Output example:
```out
one hundred and thirty-six
```
###Input example:
```in
20032 20
```
###Output example:
```out
three
```
###Input example:
```in
123 456
```
###Output example:
```out
one hundred and twenty-three
```
