ORA-01489: result of string concatenation is too long Cause: String concatenation result is more than the maximum size. Action: Make sure that the result is less than the maximum size. Reference: http://nimishgarg.blogspot.com/2012/06/ora-01489-resul…

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…

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…

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 &…
