Serialization is to store a tree in an array so that it can be later restored and Deserialization is reading tree back from the array. Now your task is to complete the function serialize which stores the tree into an array A[ ] and deSerialize which deserializes the array to tree and returns it.
Note: The structure of tree must be maintained.
The method serialize takes two arguments, the first is the root of Binary Tree and second argument is an array A[ ] which stores the serialized tree. The method deSerialize takes only one argument which is the serialized array A and returns the deserialzed tree's root . The struct Node has a data part which stores the data, pointer to left child and pointer to right child.There are multiple test cases. For each test case, this method will be called individually.
The output in the expected output will be the inorder traversal of the returned tree .
The task is to complete two method serialize and deSerialize.
1 <=T<= 30
1 <= Number of nodes<= 100
1 <= Data of a node<= 100
Example(To be used only for expected output):
1 2 L 1 3 R
10 20 L 10 30 R 20 40 L 20 60 R
2 1 3
40 20 60 10 30
Note:The Input/Ouput format and Example given above are used for system's internal purpose, and should be used by a user for Expected Output only. As it is a function problem, hence a user should not read any input from stdin/console, and should not print anything on stdout/console. The task is to complete the function specified, and not to write the full code.
