题目描述
Given two n-ary trees. Check if they are mirror images of each other or not. You are also given e denoting the number of edges in both trees, and two arrays, A[] and B[]. Each array has 2e space separated values u,v denoting an edge from u to v for the both trees.
Example 1:
Input:
n = 3, e = 2
A[] = {1, 2, 1, 3}
B[] = {1, 3, 1, 2}
Output:
1

2 3 3 2
As we can clearly see, the second tree
is mirror image of the first.
Example 2:
Input:
n = 3, e = 2
A[] = {1, 2, 1, 3}
B[] = {1, 2, 1, 3}
Output:
0

As we can clearly see, the second tree
isn't mirror image of the first.
Your Task:
You don't need to read input or print anything. Your task is to complete the function checkMirrorTree() which takes 2 Integers n, and e; and two arrays A[] and B[] of size 2e as input and returns 1 if the trees are mirror images of each other and 0 if not.
Expected Time Complexity: O(e)
Expected Auxiliary Space: O(e)
Constraints:
1 <= n,e <= 10^{5}
