special deck of cards

Malcolm is having a special deck of cards with him. Each card has some value that are just powers of two.Each value may occur any number of times.His friend gives him a challenge to find the number of non-negative integers that can be formed as a sum of some values from the deck of cards.
Help Macolm with this challenge.

Input

  • The first line of the input contains an integer T denoting the number of test cases. The description of T test cases follows.
  • The first line of each test case contains a single integer N denoting the number of cards. The second line contains N space-separated integers denoting the values present on each card.

Output

  • For each test case, output a single line containing required answer.

Constraints

  • 1 = T = 100
  • 1 = N = 50
  • Each card will contain powers of two between 1 and 2^50 inclusive.

Example

Input: 2 2 1 2 4 1 1 1 1 Output: 4 5

Explanation

Example case 1.One can make 0 (without using any cards), 1 (using 1) ,2 (using 2),3 (using 1 and 2) as sums . so the answer is 4.
