Description

In this problem we simulate a simple text editor. Given a series of keyboard input, output the final text content.
The text editing rules are defined as following:
1. Normal alphabetical input and whitespace input (abcdefg…. and ‘ ‘) directly write  after the cursor of the text content.
And four special commands started with a backslash(/) character
2. The backspace command which deletes a letter before the cursor (/backspace)
3. The newline command which creates a new line after the cursor (/newline)
4. The two navigating commands which move the cursor (/left /right)

The size of the text content is fixed to 500 characters, and the text content of testcases will not exceed 500 characters when simulating.

Use fgets(). (https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/fgets-fgetws?view=msvc-170)

Hint:

#include <stdio.h>

#define MAX_SIZE 500

char content[MAX_SIZE];
char input[MAX_SIZE];

int main()
{

    fgets(input, MAX_SIZE, stdin);

    /* your code here */

    printf("%s", content);

    return 0;
}

Input

The keyboard input sequence.
There is always a valid command(/backspace /newline /left /right) right after the backslash character.
There is no newline character at the end

Output

The final text content.

Description

You never believed in aliens until one day, while exploring a building rumored to have UFO sightings to win a bet with your friend. During a phone call with your friend, the signal became increasingly distorted. Suddenly, you lost consciousness. When you opened your eyes, three aliens with mechanical arms appeared before you in a strange space, with your limbs restrained.

Your friend, discovering your disappearance, uses Turbo Granny（高速婆婆）time-travel ability to reach you. To pinpoint your location, he sends signals that you need to respond to. 

 

You will receive T signals S. You need to return the execution result of each line to your friend.

The signals will only appear in the following formats:

1. printf("<string>");
2. printf("<string>", '<char>' / <integer>, '<char>' / <integer>, ...);
3. for(int i=N; i < M; i++) printf(...);

(The printf format in the 3rd case follows the same pattern as cases 1 and 2.)

Input

The first line contains an integer T, representing the number of signals.

The following T lines each contain a string S_i , representing the signal to process in the i-th round.

Each signal S_i is guaranteed to:

• Not contain backslashes ( \ ) or single quotes ( ' )
• ( % ) only appears in %c and %d formats
• Not contain double quotes ( " ) inside printf strings

Constraints

• 1 ≤ T ≤ 200
• 1 ≤ |S | ≤ 10⁴
• 0 ≤ |N - M | ≤ 1000

Output

Output T lines, each containing a signal S_i , representing the signal to process in the i-th round.

 

Please remember to print "\n" at the end.

Hint

You can solve this problem using the fgets function and some functions from the string.h library.

1. Use fgets(). (https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/fgets-fgetws?view=msvc-170)
2. Use strtok(). (https://cplusplus.com/reference/cstring/strtok/)
