Description: 先输入计算次数，然后输入数组个数，最后输出的是排好序的最小数组-Description
Dr lee cuts a string S into N pieces,s[1],…,s[N].
Now, Dr lee gives you these N sub-strings: s[1],…s[N]. There might be several possibilities that the string S could be. For example, if Dr. lee gives you three sub-strings {“a”,“ab”,”ac”}, the string S could be “aabac”,”aacab”,”abaac”,…
Your task is to output the lexicographically smallest S.
Input
The first line of the input is a positive integer T. T is the number of the test cases followed.
The first line of each test case is a positive integer N (1 <=N<= 8 ) which represents the number of sub-strings. After that, N lines followed. The i-th line is the i-th sub-string s[i]. Assume that the length of each sub-string is positive and less than 100.
Output
The output of each test is the lexicographically smallest S. No redundant spaces are needed.
Sample Input
1
3
a
ab
ac
Sample Output

Description: This document provides implementation instructions for the DDR3 interface-This document defines the DDR3 SDRAM specification, including features, functionalities, AC and DC
characteristics, packages, and ball/signal assignments. The purpose of this Specification is to define the
minimum set of requirements for JEDEC compliant 512 Mb through 8 Gb for x4, x8, and x16 DDR3
SDRAM devices. This specification was created based on the DDR2 specification (JESD79-2) and some
aspects of the DDR specification (JESD79). Each aspect of the changes for DDR3 SDRAM operation were
considered and approved by committee ballot(s). The accumulation of these ballots were then incorporated
to prepare this JESD79-3 specification, replacing whole sections and incorporating the changes into
