Write a program to read a string and return a modified string based on the following rules.

Return the String without the first 2 chars except when

1.   keep the first char if it is 'j'

2.   keep the second char if it is 'b'.

Include a class UserMainCode with a static method getString which accepts a string. The return type (string) should be the modified string based on the above rules. Consider all letters in the input to be small case.

Create a Class Main which would be used to accept Input string and call the static method present in UserMainCode.

Input and Output Format:

Input consists of a string with maximum size of 100 characters.

Output consists of a string.

Refer sample output for formatting specifications.
