WebA palindrome is a word w such that w = wR.IfL is a language over Σ, i.e., L ⊆ Σ∗,wesaythatL is palindromic if every word w ∈ L is a palindrome. Let k ≥ 2 be an integer. A word y is a k-power if y canbewrittenasy = xk for some non-empty word x.Ify cannot be so written for anyk ≥ 2, then y is primitive. A 2-power is typically referred ... WebFeb 14, 2015 · Palindromic Squares February 14, 2015 JoeDubs, Synchronicity A palindrome is a word, phrase, or number which reads the same backward or forward. The squares of 10, 11, 12, and 13 fit the bill. It breaks down after that since 15 squared is 225, and 51 squared is 2601. Why only these 4 or arguably 3 numbers?

WebJul 22, 2013 · Palindromic Squares. Rob Kolstad. Palindromes are numbers that read the same forwards as backwards.The number 12321 is a typical palindrome. Given a number base B (2 <= B <= 20 base 10), print all theintegers N (1 <= N <= 300 base 10) such that … WebAug 17, 2013 · OK, here's my program. It caches valid suffixes for squares (i.e. the values of n^2 mod 10^k for a fixed k), and then searches for squares which have both that suffix and start with the suffix reversed. This program is very fast: in 24 seconds, it lists all the palindromic squares up to 10^24.

Let i be the first half of the digits in R. For eg. if i = 123, then R = 12321 or R = 123321. Thus we can iterate through these all these digits.
