WebThe easiest method is to simply count palindromes of length exactly n. For even n, this is 26 n / 2, and for odd n, 26 ( n − 1) / 2. So, if we include lengths 1 and 2, we want to add 26 + 26 + 26 2 + 26 2 + 26 3 + 26 3 + …. If n is even, this is just twice the sum of a geometric series. If n is odd, you get one extra term to add at the end. Web【基础】回文平方数 Palindromic Squares. 查看题目 登录后递交 讨论 ; 题解 ; 文件 信息. ID 1537 ...
