Given a Binary Tree. Check whether it is Symmetric or not, i.e. whether the binary tree is a **Mirror image of itself** or not.

**Example 1:**

**Input:
** 5
/ \
1 1
/ \
2 2**
Output: **True**
Explanation: **Tree is mirror image of
itself i.e. tree is symmetric

**Example 2:**

**Input:
** 5
/ \
10 10
/ \ \
20 20 30**
Output: **False

**Your Task:**

You don't need to read input or print anything. Your task is to complete the function **isMirror()** which takes the root of the Binary Tree as its input and returns True if the given Binary Tree is a same as the Mirror image of itself. Else, it returns False.

**Expected Time Complexity:** O(N).

**Expected Auxiliary Space:** O(Height of the Tree).

**Constraints:**

0<=Number of nodes<=100

**Note:**The **Input/Ouput **format and **Example **given are used for system's internal purpose, and should be used by a user for **Expected Output** only. As it is a function problem, hence a user should not read any input from stdin/console. The task is to complete the function specified, and not to write the full code.
