**Python**.Unlike linked lists, one-dimensional arrays, and other linear data structures, which are traversed in linear order, trees can be traversed in multiple ways in depth-first order (preorder, inorder, and postorder) or breadth-first order (level order

**traversal**). .. The input and output arrays are simply traversed, respectively, according to "row-major" rules. Suppose we want to reshape a shape- (2,3,4) array into a shape- (6,4) array. This process would be carried out as follows: Reshaping a shape- (2,3,4) into a shape (6,4) array using NumPy's default "row-major" ordering. 2021. 11. 30. · Graph in

**matrix**script is a N X M grid of strings. It consists of alphanumeric characters, spaces and symbols (!,@,#,$,%,&). To decode the script, Neo needs to read each column and select only the alphanumeric characters and connect them. Neo reads the column from top to bottom and starts reading from the leftmost. Solution. The example result can be achieved by 6 ( = m + n - 1) linear scans: Let i be the number of scans, starting from 0, the even scans are going up-right, while the odd scans are going down-left. The starting point of each scan: i % 2 == 0 (up-right): if i < m, there are more rows down below (like 9 in the example), start from the first. Adjacency
