Dequeue(); if (left == null && right == null) continue; if(left == null || right == null) return false; if(left.val != right.val) return false; // enqueue the element in a way such that they are mirror elements treeNodes.Enqueue(left.left); treeNodes.Enqueue(right.right); ...
For example, the following are some binary trees that have a symmetric structure: Practice this problem The tree has a symmetric structure if the left and right subtree mirror each other. Two trees mirror each other if all the following conditions are satisfied: Both trees are empty, or both ...
The base case is when t1 and t2 are both null, they are mirror of each other. Solution 2. Iterative using level order traversal There are 2 ways of doing this. 1. do a regular level order traversal from left to right at each level, then check if all nodes of each level are palindr...
If I could talk to my twelve-year-old self, what would I say? Fight the boys back with insults? Laugh at them and tell them I loved my face? Push them off their bikes? The wisest way would have been to heed my mother: ‘Silly boys showing off…you are beautiful inside and out’...
