Problem Description

There is an old country and the king fell in love with a devil. The devil always asks the king to do some crazy things. Although the king used to be wise and beloved by his people. Now he is just like a boy in love and can’t refuse any request from the devil. Also, this devil is looking like a very cute Loli.

Let us continue our story, z*p(actually you) defeat the ‘MengMengDa’ party’s leader, and the ‘MengMengDa’ party dissolved. z*p becomes the most famous guy among the princess’s knight party.

One day, the people in the party find that z*p has died. As what he has done in the past, people just say ‘Oh, what a nice boat’ and don’t care about why he died.

Since then, many people died but no one knows why and everyone is fine about that. Meanwhile, the devil sends her knight to challenge you with Algorithm contest.

There is a hard data structure problem in the contest:

There are n numbers a_1,a_2,…,a_n on a line, everytime you can change every number in a segment [l,r] into a number x(type 1), or change every number a_i in a segment [l,r] which is bigger than x to gcd(a_i,x) (type 2).

You should output the final sequence.

Input

The first line contains an integer T, denoting the number of the test cases.
For each test case, the first line contains a integers n.
The next line contains n integers a_1,a_2,…,a_n separated by a single space.
The next line contains an integer Q, denoting the number of the operations.
The next Q line contains 4 integers t,l,r,x. t denotes the operation type.

T<=2,n,Q<=100000
a_i,x >=0
a_i,x is in the range of int32(C++)

Output

For each test case, output a line with n integers separated by a single space representing the final sequence.
Please output a single more space after end of the sequence

线段树的变式,设node[u].num=x表示节点u所管理的区间的值全是x,如果node[u].num=-1,表示这个区间的值不是统一的。每次对于操作1,直接将区间被包含的节点的num赋值为x,同时对相应节点打标记。对于操作2,如果这个节点管理的区间被包含并且值是统一的,直接取gcd并对节点打标记即可。否则,继续往下找直到找到值是统一并且被包含的区间,再取gcd并打标记。
