function to con full binary tree using its preorder traversal and preorder traversal of its mirror tree
static void conBinaryTree ( Node root , int [ ] pre , int [ ] preMirror , int size ) { INT preIndex = new INT ( 0 ) ; int preMIndex = 0 ; root = conBinaryTreeUtil ( pre , preMirror , preIndex , 0 , size - 1 , size ) ; printInorder ( root ) ; }
