Chef belongs to a very rich family which owns many gold mines. Today, he brought N gold coins and decided to form a triangle using these coins. Isn't it strange?
Chef has a unusual way of forming a triangle using gold coins, which is described as follows:

He puts 1 coin in the 1^st row.
then puts 2 coins in the 2^nd row.
then puts 3 coins in the 3^rd row.
and so on as shown in the given figure.

Chef is interested in forming a triangle with maximum possible height using at most N coins. Can you tell him the maximum possible height of the triangle?

Input
The first line of input contains a single integer T denoting the number of test cases.
The first and the only line of each test case contains an integer N denoting the number of gold coins Chef has.

Output
For each test case, output a single line containing an integer corresponding to the maximum possible height of the triangle that Chef can get.

Constraints

1 ≤ T ≤ 100
1 ≤ N ≤ 10^9

Example

Input
3
3
5
7

Output
2
2
3

Explanation

Test 1: Chef can't form a triangle with height > 2 as it requires atleast 6 gold coins.
Test 2: Chef can't form a triangle with height > 2 as it requires atleast 6 gold coins.
Test 3: Chef can't form a triangle with height > 3 as it requires atleast 10 gold coins.
