题目链接:http://codeforces.com/problemset/problem/608/B 题目意思:给出两个字符串 a 和 b,然后在b中找出跟 a 一样长度的连续子串,每一位进行求相减的绝对值然后相加(这个讲得有点绕),直接举个例子就很容易理解了. 假设a = 01,b = 00111, 符合条件的b的子串有:00, 01, 11, 11 然后: |01-00| = |0-0| + |1-0| = 1,  |01-01| = |0-0| + |1-1| = 0, |01-11|…

题目: http://codeforces.com/contest/608/problem/B 字符串a和字符串b进行比较,以题目中的第一个样例为例,我刚开始的想法是拿01与00.01.11.11从左到右挨个比较,希望能找到一些规律,结果并没有... 其实,如果我们能从整个比较过程来看这个问题,整个过程就没有那么难.题目要求的东西,其实就是a字符串和b字符串子串每次比较的不同的个数的总和,当我们像上面那个思路,拿a字符串每次移动一位,和b进行比较的时候,从整个过程来看,就相当于a的每一个元素从前…
