Read the keyboard simulation commands from input, and produce the text.

Input

There are multiple tests cases.

Each test case contains several lines, which may be one of the following:

Left: move the cursor to the previous character. Keep still if it is before the first character.
Right: move the cursor to the next character. Keep still if it is after the last character.
CtrlLeft: move the cursor to the first character of the current word; if the cursor is already at the first character of the word, move it to the first character of the previous word; if there is no previous word, the cursor will keep still. The word here is defined as a continued character sequence with no embedded whitespace.
CtrlRight: move the cursor to the first character of the next word; if there is no next word, the cursor will keep still.
Home: move the cursor before the first character of the line.
End: move the cursor after the last character of the line.
Insert: switch the Insert/Overwrite mode. (At the beginning the mode is Insert) In the Overwrite mode, the character input will overwrite the original character in the text except before an enter.
Delete: delete the character after the cursor.
Backspace: delete the character before the cursor.
Blankspace: input a blank space.
Press s: input a string s. (s contains only readable characters)
Enter: input an newline character.
EndWithEndl: append an Enter after the text and terminate the test case.
EndOfInput: input is terminated with this command, do not produce output.

There will be a blank line to separate subsequent test cases.
