PROGRAMMING:A-B
This problem requires you to calculate $$A-B $$. However, the trouble is that both $$a $$and $$B $$are strings - that is, delete all the characters contained in the string $$B $$from the string $$a $, and the remaining characters are composed of the string $$A-B $$.
###Input format:
Input gives the strings $$a $$and $$B $$in two lines. The length of both strings should not exceed $$10 ^ 4 $, and ensure that each string is composed of visible ASCII and white space characters, and ends with a new line character.
###Output format:
Print out the result string of $$A-B $$in one line.
###Input example:
```in
I love GPLT! It's a fun game!
aeiou
```
###Output example:
```out
I lv GPLT! It's fn gm!
```
