Problem :- Given an N bit binary number, find the 1's complement of the number. The ones' complement of a binary number is defined as the value obtained by inverting all the bits in the binary representation of the number (swapping 0s for 1s and vice versa).

Input:

The first line of input takes the number of test cases, T. Then T test cases follow. The first line of each test case takes the number of bits, N. The second line of each test case takes N space separated integers denoting the N bits of the binary number.

Output:

Print the 1's complement for each test case in a new line.

    while(t--)
    {
        int n,i,j,sum,res=0;
        cin>>n;
        int arr[n];
        for(i=0;i<n;i++)
        cin>>arr[i];
        for(i=0;i<n;i++)
        {
            if(arr[i]==1)
            cout<<"0 ";
            else
            cout<<"1 ";
        }
        cout<<endl;
    }
    return 0;

}
