WebApproach: Use Depth-First Search (DFS) Create a boolean visited [] array. Start DFS from any vertex and mark the visited vertices in the visited [] array. Once DFS is completed check the iterate the visited [] and count all the true's. WebOne way to serialize a binary tree is to use preorder traversal. When we encounter a non-null node, we record the node's value. If it is a null node, we record using a sentinel value such as '#'. For example, the above binary tree can be serialized to the string "9,3,4,#,#,1,#,#,2,#,6,#,#", where '#' represents a null node.
