Diagonal traversal of binary tree practice
WebShort trick to mark the node with a diagonal distance value: Firstly, mark the root node as 0. Mark the right-side series of a root node as 0 shown as below: In simple words, we can say that 0 th diagonal is "a c g m r". … WebGiven an m x n matrix mat, return an array of all the elements of the array in a diagonal order. Example 1: Input: mat = [[1,2,3],[4,5,6],[7,8,9]] Output: [1,2,4,7,5,3,6,8,9] Example 2: Input: mat = [[1,2],[3,4]] Output: [1,2,3,4] …

Space Complexity: O(n) as extra space for storing the left child of the current nodes in a queue, where n is the number of nodes in the Binary Tree.. Approach 2 - Recursive Approach. … WebApr 10, 2024 · If not, travel to the right subtree. Repeat until you reach a leaf node. The right-most node is also defined in the same way with left and right exchanged. For example, boundary traversal of the following tree is “20 8 4 10 14 25 22”. This is how we write the traversal: root : 20. left- boundary nodes: 8. leaf nodes: 4 10 14 25.
WebIt is clear that '1 3 7' is the first diagonal path '2 5 6' is the second and '4' is the third diagonal path. But 5 and 6 have the same level and same diagonal path, so we need to consider a node that comes first in the pre-order traversal. Hence the diagonal path of the above binary tree is 1 3 7 2 5 6 4. Test case 2:
