Given a Binary Tree, check if all leaves are at same level or not.

Example 1:

Input: 
            1
          /   \
         2     3

Output: 1

Explanation: 
Leaves 2 and 3 are at same level.

Example 2:

Input:
            10
          /    \
        20      30
       /  \        
     10    15

Output: 0

Explanation:
Leaves 10, 15 and 30 are not at same level.


Your Task: 
You dont need to read input or print anything. Complete the function check() which takes root node as input parameter and returns true/false depending on whether all the leaf nodes are at the same level or not.

 

Expected Time Complexity: O(N)
Expected Auxiliary Space: O(height of tree)

 

Constraints:
1 ≤ N ≤ 10^3
