palindrome (Definition)

A palindrome is a number which yields itself when its digits are reversed. Some palindromes (in base 10) are :

  • 121
  • 2002
  • 314159951413

Clearly one can construct palindromes of arbitrary length by taking any number and appending to it a reversed copy of itself or of all but the last digit.

The concept of palindromes can also be extended to sequences and strings.
