John是个小列车站的站长，每次列车在这里重新编组时他就很烦恼。因为站上只有一个人字形的编组轨道(如图)，所有的列车车厢都是从人字轨的右边依次进去，从左边出来。但有一些编组顺序John总编不出来，John怀疑有些编组顺序是不可能完成的，可John又找不出那些是顺序是可以编组出，那些不可以。请你写一个程序帮助John辨别哪些编组可以完成，哪些不能完成。
输入：
第一行是一个整数K，表示有多少个测试用例，以后每行一个测试用例，每行为n+1个整数，第一个整数为n 表示有多少节车厢，后面n个整数表示需要编组成的顺序。比如说3节车厢，按照1，2，3依次入轨编组，可以在左边形成1 2 3，1 3 2，2 1 3，2 3 1，321。
输出：
每行输出一个测试用例的结果。如果可以编组输出Yes，否则输出No。
Sample Input
2
3 3 1 2
4 1 2 3 4
Sample Output
No
Yes

John is the webmaster of a small train station, he is very trouble each train regrouping. Turn inside out from the left because the right side of the station is only a grouping of chevron track (pictured), all train compartments are herringbone track. Marshalling the order of John editor-in-chief but not out, John suspected some grouping order is impossible, John could not find those order can marshalling those who can not. You write a program to help John to identify which grouping can be done, what can not be completed.
Input:
The first line is an integer K, the number of test cases, each subsequent line of a test case, every behavior n integer, an integer n represents the number of cars behind n integers need grouped order. For example, three cars, in accordance with 1, 2, 3, in turn orbit grouping, formed in the left 12 3,1 3 2,2 3,2 3 1,321.
