Diagonal traversal of tree gfg
WebMar 16, 2024 · Given a matrix A[][] of size N*M and a 2D array Q[][] consisting of queries of the form {X, K}, the task for each query is to find the position of the K th occurrence of element X in the matrix when the diagonal traversal from left to right is performed. If the frequency of element X in the matrix is less than K, then print “-1”.. Examples: WebAug 22, 2024 · Also when we will traverse the level from bottom we will mark flag as 0 so that next time we traverse the tree from left to right and then decrement the value of j so that next time we visit the level just above the current level. Repeat the whole process until the binary tree is completely traversed. Below is the implementation of the above ...

WebSep 27, 2024 · Output. Principal Diagonal:18 Secondary Diagonal:18. Time Complexity: O (N*N), as we are using nested loops to traverse N*N times. Auxiliary Space: O (1), as we are not using any extra space. Method 2 ( Efficient Approach): In this method, we use one loop i.e. a loop for calculating the sum of both the principal and secondary diagonals: WebWe will do an inorder traversal of the binary tree. While doing this, we will keep track of the distance in a diagonal direction. Whenever we move in the left direction we add 1 to the diagonal distance and if we moved in the …
