A B+ tree of order 3 is generated by inserting 89, 9 and 8. The generated B+ tree is __________

To generate a B+ tree of order 3 by inserting 89, 9, and 8, follow these steps:

1. Start with an empty B+ tree.
2. Insert the first number, 89. Since the tree is empty, 89 becomes the root of the tree.
3. Next, insert the second number, 9. Since 9 is less than 89, it becomes the left child of 89.
4. Finally, insert the third number, 8. Since 8 is less than 9, it becomes the left child of 9.

So, the generated B+ tree is:

   89
  /
 9
/
8

Please note that in a B+ tree, all data is stored at leaf nodes and the internal nodes act as a multilevel index to the leaf nodes. The tree described above is a simplified representation. In a real B+ tree of order 3, each node (except for the root) would have between 2 and 3 children.
