The Smallest String Concatenation 题目链接:http://codeforces.com/problemset/problem/632/C ——每天在线,欢迎留言谈论. 题目大意: 给你n个字符串,相加后 字典序最小 思路: 只需要保证每个相邻的两个字符串组合后 s1+s2>s2+s1 即可. 用sort()快速排序,最后依次输出即可! AC代码: #include <iostream> #include <string> #include &…

Description You're given a list of n strings a1, a2, ..., an. You'd like to concatenate them together in some order such that the resulting string would be lexicographically smallest. Given the list of strings, output the lexicographically smallest c…

题目链接 给出n个字符串, 将他们连在一起, 求连玩之后字典序最小的那种情况. 按a+b<b+a排序.... #include <iostream> #include <vector> #include <cstdio> #include <cstring> #include <algorithm> #include <cmath> #include <map> #include <set> #inclu…

参考https://www.liaoxuefeng.com/article/001411306573093ce6ebcdd67624db98acedb2a905c8ea4000/ Java 8终于引进了lambda表达式,这标志着Java往函数式编程又迈进了一小步. 在Java 8以前的代码中,为了实现带一个方法的接口,往往需要定义一个匿名类并复写接口方法,代码显得很臃肿.比如常见的Comparator接口: String[] oldWay = "Improving code with Lamb…

Using the string concatenation operator repeatedly to concatenate n strings requires time quadratic in n. It's an unfortunate consequence of fact that strings are immutable(Item 15). // Inappropriate use of string concatenation - Performs horribly! p…
