Frank_DD has a sequence a of length n.
For each operation, he selects a number ai(1in) and changes it to 2ai.
Frank_DD wants to know the minimum number of operations to change the sequence a to a non-descending sequence.

输入格式

The first line of the input contains one integer TT ((1T5 )) --- the number of test cases. Then T test cases follow.
In each test case:
The first line contains a single integer n(1n105) --- the length of sequence a.
The second line contains nn integers a1,a2,,an (1ai105) --- the sequence a.

输出格式

For each test case, print a single integer in a single line --- the minimum number of operations to change the sequence aa to a non-descending sequence.
