Create Target Array

You are given an array of integers. Starting with an array of 'N' elements consisting of all 1’s, you need to create the given array. To do so, you can update any index of the current array, with the sum of all elements present in the array.

For example:

Consider the starting array: [1, 1, 1, 1]. You can update any index of this array with 4 (the sum of all elements of the current array).

You can perform the above operations any number of times. Your task is to check if it is possible to get the target array from the starting array of all 1’s or not.

Input Format:

The first line contains an integer ‘T’ which denotes the number of test cases or queries to be run. Then the test cases are as follows.

The first line of each test case contains a single integer ‘N’, denoting the size of the target array.

The next line contains ‘N’ space-separated integers denoting elements of the target array.

Output Format:

For each test case, print 1 if it is possible to create the target array, otherwise print 0.

Print the output of each test case in a separate line.

Note:

You don’t need to print anything; It has already been taken care of. Just implement the given function.

Constraints:

1 <= T <= 10
1 <= N <= 10^4
1 <= X <= 10^9
