两种解法,动态规划和KMP变种 动态规划,类似于lcs的解法,数组flag[i][j]记录s从i到j是不是回文 首先初始化,i>=j时,flag[i][j]=true,这是因为s[i][i]是单字符的回文,当i>j时,为true,是因为有可能出现flag[2][1]这种情况,比如bcaa,当计算s从2到3的时候,s[2]==s[3],这时就要计算s[2+1] ?= s[3-1],总

这道题的核心是考回文数字的判断。判断回文的手法基本可以分两类。 1.转换成字符串来判断,也是参考答案里的做法。(思路比较简单,这里不在熬述) 2.数学方式来判断(只能判断数字),使用mod的方法。这个方法的好处是,不要把数字转换成相应进制的表达方式然后再判断。 手法比较巧妙。 下面我来讲解下方法2. 首先我们从最简单的十进制讲起,比如有个数 123。 十进制的表示: 1
