Well the title says it all.

• Standard loopholes apply
• Nothing to read from stdin, and output goes to stdout
• 1-byte-long programs are... nonsense. They don't qualify
• A program with a single byte repeated is also a nonsense (like aaa)
• Please mark it out if your program is a palindrome

Sample:

A program with source code

abcde

should output

edcba

Because this is a code-golf, the shortest program wins!
