Identical Trees Problem Statement
Given two binary trees with 'N' and 'M' nodes respectively, determine if the two trees are identical. Return true
if they are identical, otherwise return false
.
Input:
The first line contains an integer T
denoting the number of test cases.
The first line of each test case contains elements in level order for the first binary tree, with node values separated by a space. Use -1 for null nodes.
The second line of each test case contains elements in level order for the second binary tree, formatted similarly.
Output:
For each test case, return True
if the trees are identical, or False
otherwise. Print each result on a new line.
Example:
Input:
1
1 2 3 4 -1 5 6 -1 7 -1 -1 -1 -1 -1 -1
1 2 3 4 -1 5 6 -1 7 -1 -1 -1 -1 -1 -1
Output:
True
Constraints:
1 ≤ T ≤ 10
0 ≤ N ≤ 10^5
0 ≤ M ≤ 10^5
1 ≤ Node Data ≤ 10^9
- Time limit: 1 sec
Note:
You are not required to print anything; it has already been taken care of in the function implementation.
