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|

Given a list of unique words. Find all pairs of distinct indices (i, j) in the given list, so that the concatenation of the two words, i.e.words[i] + words[j] is a palindrome. Example 1:Given words = ["bat", "tab", "cat"]Retu

Saitama accidentally destroyed a hotel again. To repay the hotel company, Genos has volunteered to operate an elevator in one of its other hotels. The elevator is special - it starts on the top floor, can only move down, and has infinite capacity. Fl
