C. The Smallest String Concatenation time limit per test 3 seconds memory limit per test 256 megabytes input standard input output standard output You're given a list of n strings a1, a2, ..., an. You'd like to concatenate them together in some order…

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…

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 &…

Given the root of a binary tree, each node has a value from 0 to 25 representing the letters 'a' to 'z': a value of 0 represents 'a', a value of 1 represents 'b', and so on. Find the lexicographically smallest string that starts at a leaf of this tre…
