UVa:11584 Partitioning by Palindromes

犯了一个SB错误。假如说读str+1，那么str+1的最后一个字符的下标应该是strlen（str+1），\0是第strlen（str+1）+1。这点和读str不一样，不要搞错了。一开始想了个类似是区间dp的思路，对于给定区间分别枚举截点求它们的和，三重循环结果超时了。后来想出来了这个代码，我今天脑袋有点晕乎乎的，也说不清楚它的正确性。。dp[j][i]表示区间ji之间的最少回文串数，对于每个终点

UVa:10739 String to Palindrome

其实对于一个字符串第一个和最后一个字符不同的情况下，只有三种操作，删除第一个，删除最后一个，或者替换其中一个。这样对应三种递归方式。当然如果第一个和最后一个相同，那么直接递归不包括这俩字符的串即可。当只有一个字符或者两个字符而且成为回文的时候终止递归，返回值为0。不难写。 #include #include #include #include #include #definelllong

Palindrome Number

原题链接问题：给定个int数，判断其是否为回文数。分析：对于回文字符串我们很熟悉，但是题目中要求不能用额外的存储空间，所以不能将其转换为字符串来判断。对于将参数进行逆置的方法，可能会存在溢出的问题，所以题目中也不建议用这种方法，那么还的考虑用回文字符串的比较方式，我们在判断回文串的时候，策略是用最后的和最前的比，相同继续，不同就返回false。若前后相遇则表示是回文，返回true。那么这个怎么获取
