A repdigit is a positive number composed out of the same digit. Create a function that takes an integer and returns whether it's a repdigit or not.

Examples

is_repdigit(66) ➞ True

is_repdigit(0) ➞ True

is_repdigit(-11) ➞ False

Notes

  • The number 0 should return True (even though it's not a positive number).
  • Check the Resources tab for more info on repdigits.
