Topic and analysis

The preorder traversal and intermediate order traversal of a given tree are given to find the subsequent traversal.

Input

Abdec

Dbeac

Output

Debca

3. Implementation code:

# include # include using namespace std;string S1 = "abdec"; / / preorder traversal of string S2 = "dbeac"; / / traversal of void calc in the middle order {int m=s2.find (S1 [L1]) {int m=s2.find (S1 [L1])
