Problem Description

Our lovely KK has a difficult mathematical problem:he has a
N(1≤N≤1018)
meters steel,he will cut it into steels as many as possible,and he doesn't want any two of them be the same length or any three of them can form a triangle.

 

Input

The first line of the input file contains an integer
T(1≤T≤10),
which indicates the number of test cases.



Each test case contains one line including a integer
N(1≤N≤1018),indicating
the length of the steel.

 

Output

For each test case, output one line, an integer represent the maxiumum number of steels he can cut it into.

 

Sample Input

1
6

 

Sample Output

3

Hint

1+2+3=6 but 1+2=3  They are all different and cannot make a triangle.
