WebFeb 19, 2016 · The 10 comes from the sum of all the palindromes in one digit. Since there are 10 palindromes for every thousand, that is where they come from. For Example, The Palindromes for 1000 is 1001 to 1991, so if we were to find the sum, we have to add all the ones, or multiply it by 10 Share Cite Follow answered Apr 4, 2016 at 13:27 Ashwath …

WebAlmost all palindromic numbers are composite, for any base . 11 is the only palindromic prime with an even number of digits because all palindromic numbers with an even number of digits can be divided by 11, which means they are not primes. Webten’s place. The three digit palindromes are 101, 111, 121, 131, 141, 151, 161, 171, 181, 191, 202, 212, 222, . . . One could list all of the three digit palindromes to see how many there are, but a more general formula can be derived to find the number of k-digit palindromes, where k is any whole number greater than one.
Webpalindromes = [x for x in xrange (min, max) if isPalindrome (x)] The only way you can do this and have a non-linear algorithm is to generate the palindromes yourself, instead of testing. A palindrome can be generated by taking a previous palindrome, and adding the same number to the left and right side, so that is a starting point.
