Note that this is not the same as Print the alphabet four times.
This task is to write a program to generate four copies of each letter of the English alphabet, one letter per line, on standard output:
A
A
A
A
B
B
B
B
etc.
The output should include newlines after each letter.
Lowercase letters and/or extra whitespace are acceptable.
The solution must be a complete program.
This is code-golf so answers will be scored in bytes with a lower score being the goal.
