#### Given a Binary Tree, check whether every node in the given tree has the same number of nodes on the left and right sides.

##### For Example :

```
Consider the Binary Tree below :
```

```
The number of nodes on the left side of node 6 is 3 while on the right side it is 1. Hence the answer for the above binary tree is false.
```

```
The first line contains a single integer ‘T’ denoting the number of test cases.
The first line of each test case contains the elements of the binary tree in the level order form separated by a single space.
If any node does not have a left or right child, take -1 in its place. Refer to the example below.
```

```
1
2 3
-1 4 -1 -1
5 -1
-1 -1
Explanation :
Level 1 :
The root node of the tree is 1
Level 2 :
Left child of 1 = 2
Right child of 1 = 3
Level 3 :
Left child of 2 = null (-1)
Right child of 2 = 4
Left child of 3 = null (-1)
Right child of 3 = null (-1)
Level 4 :
Left child of 4 = 5
Right child of 4 = null (-1)
Level 5 :
Left child of 5 = null (-1)
Right child of 5 = null (-1)
The first not-null node (of the previous level) is treated as the parent of the first two nodes of the current level. The second not-null node (of the previous level) is treated as the parent node for the next two nodes of the current level and so on.
The input ends when all nodes at the last level are null (-1).
Note: The above format was just to provide clarity on how the input is formed for a given tree.
The sequence will be put together in a single line separated by a single space. Hence, for the above-depicted tree, the input will be given as:
1 2 3 -1 4 -1 -1 5 -1 -1 -1
```

```
For each test case, return True or False denoting whether the given binary tree satisfies the above condition.
Output for each test case will be printed in a separate line.
```

##### Note :

```
You are not required to print anything; it has already been taken care of. Just implement the function.
```

##### Constraints :

```
1 <= T <= 100
1 <= number of nodes <= 1000
1 <= nodeVal <= 10^9
Time Limit: 1 sec
```

##### Sample Input 1 :

```
1
2 3 4 -1 -1 -1 -1
```

##### Sample Output 1 :

```
True
```

##### Explanation For Sample Output 1 :

```
For the given test case, There is a binary tree of 3 nodes only. Node with value 2 has one node on the left and another on right. Hence each node has the same number of nodes on the left and right parts.
```

##### Sample Input 2 :

```
1
1 2 3 4 5 6 7 -1 -1 -1 -1 -1 -1 -1 -1
```

##### Sample Output 2 :

```
True
```
