Given a sentence containing few instances of "Ctrl + C" and "Ctrl + V", return the sentence after those keyboard shortcuts have been applied!
- "Ctrl + C" will copy all text behind it.

-  "Ctrl + V" will do nothing if there is no "Ctrl + C" before it.

- A "Ctrl + C" which follows another "Ctrl + C" will overwrite what it copies.
Examples
<br>#Example 1<br>keyboardShortcut("the egg and Ctrl + C Ctrl + V the spoon") output = "the egg and the egg and the spoon"<br><br>#Example 2<br>keyboardShortcut("WARNING Ctrl + V Ctrl + C Ctrl + V")<br>output= "WARNING WARNING"<br><br>#Example 3<br>keyboardShortcut("The Ctrl + C Ctrl + V Town Ctrl + C Ctrl + V")<br>output = "The The Town The The Town"<br>
Notes
- Keyboard shortcut commands will appear like normal words in a sentence but shouldn’t be copied themselves (see example #2).

- Pasting should add a space between words.
