Continuously print a random character (a-z, A-Z, 0-9) not separated by a newline (\n).

Expected output

b7gFDRtgFc67h90h8H76f5dD55f7GJ6GRT86hG7TH6T7302f2f4 ...

Note: output should be randomised.


  1. Output must be continuous (i.e. never ending),
  2. Output may not comprise of newlines,
  3. Output must be random, and should not have a set seed (i.e: produce the same output every time)
  4. Output must be only composed of characters: a-z, A-Z, 0-9.
  5. No loopholes, regarding programming language version(s). Use only the tools available with that programming language, no third-party packages, modules, or other addons.
