Write a program that outputs
Do not repeat yourself!
Your program code must respect the following constraints :
- its length must be an even number
- each character that is in position
nis an integer > 0) must be equal to the character in position
2n-1. The second character of the program is equal to the first, the fourth is equal to the third, etc.
Newlines count as characters!
This is code-golf, so the shortest code wins!
HHeellllooWWoorrlldd is a valid program
HHeello are incorrect
You can use this CJam script to verify that your source code is valid. Simply paste your code into the "Input" box and run the script.
DDDooo nnnooottt rrreeepppeeeaaattt yyyooouuurrrssseeelllfff!!!would be a valid answer in Trigger \$\endgroup\$
