逆转:串的逆转就是具有相同符号单顺序相反的字符串。例如,如果s=abc(a、b和c是字母表中符号),那么s 的逆转就是cba。一个与自身相反的字符串(例如,s=madam,逆转还是madam)被称为回文 palindrome,它还包括空字符串和所有长度为1的字符串。四、串的实现...
I think I just figured out how it's done and made a code for it, honestly this way of Palindrome checking is kinda new to me, as I'm more familiar with the common method, by comparing the characters from each of the opposite end of the string and don't usually bother removing white...

题目链接:Codeforces 486C Palindrome Transformation 题目大意:给定一个字符串,长度N。指针位置P,问说最少花多少步将字符串变成回文串。 解题思路:事实上仅仅要是对称位置不同样的。那么指针肯定要先移动到这里,改动字符仅仅须要考虑两种方向哪种更优即 可。
