WebSep 7, 2024 · Now since R is a palindrome, the first half of the digits of R can be used to determine R up-to two possibilities. 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. Also each possibility can have either odd or even number of digits in R. WebBy default, a string is considered palindromic if its list of characters is palindromic: The first nine coefficients of this series expansion are special palindromic numbers: Those coefficients can also be generated as squares of repunits 1, 11, 111, etc.: WebThe first few numbers whose squares are palindromic are 1, 2, 3, 11, 22, 26, ... (OEIS A002778 ), and the first few palindromic squares are 1, 4, 9, 121, 484, 676, ... (OEIS A002779 ). There are no palindromic square -digit numbers for , 4, 8, 10, 14, 18, 20, 24, 30, ...
