Sandu, a teacher in Chefland introduced his students to a new sequence i.e.
0,1,0,1,2,0,1,2,3,0,1,2,3,4........
The Sequence starts from 0 and increases by one till $i$(initially i equals to 1), then repeat itself with $i$ changed to $i+1$
Students being curious about the sequence asks the Nth element of the sequence. Help Sandu to answer the Students

-----Input:-----
- The first-line will contain $T$, the number of test cases. Then the test case follows. 
- Each test case contains a single numbers N.

-----Output:-----
Print the Nth element of the sequence

-----Constraints-----
- $1 \leq T \leq 1000$
- $1 \leq N  \leq 10^{18}$

-----Sample Input:-----
5
8
9
20
32
109

-----Sample Output:-----
2
3
5
4
4
