Top view of binary tree using map
WebNov 29, 2024 · The first node of every line will be my top view. Approach : First we have to make a queue of pair which have nodes and their respective +ve and -ve indexes. Then we need a map data structure to store the lines and the nodes. This map will store the data in the form of sorted orders of keys (Lines). Here we will follow the level order traversal ... WebA map element is a key and value pair that corresponds to one object and maps it to another. The Spark engine can read and write map data from complicated files, as well as pass map data through mapping. A key-value pair is analogous to looking up a word in a dictionary. The key is the word, and the value is the term's meaning or definition.
