Consider a search engine that automatically recognizes escape sequences in the C language. If a string contains an escape sequence, the effect of the escape sequence on the string must be taken into consideration while printing the string. Each escape sequence performs a specific function:

• \b - Backspace. Erases the last character
• \n - Newline. Prints a new line

You are given multiple input lines containing one string each. The string may contain the escape sequences mentioned above.

Write a program to print the output after accounting for all the escape sequences.

Input format

• The input consists of multiple lines. Each line contains a string.

Output format

Print the strings after applying the escape sequences.

Note:

Backspace does not take you to the previous line.
