<P> A palindrome is a word , number , phrase , or other sequence of characters which reads the same backward as forward , such as madam or racecar or the number 10201 . Sentence - length palindromes may be written when allowances are made for adjustments to capital letters , punctuation , and word dividers , such as `` A man , a plan , a canal , Panama ! '' , `` Was it a car or a cat I saw ? '' or `` No ' x ' in Nixon '' . </P>
