One-to-serialize a binary tree is-to-use pre-order 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 # . _9_ / 3 2 /\ / 4 1 # 6/\/\ /# # # # # # # # # #For example, the above binary tree can "9,3,4,#,#,1,#,#,2,#,6,#,#" is serialized to the string, where # represents a null node.Given a string of comma separated values, verify whether it
