[5, 12] [20, 30]B+ Tree Rules (Order 4) Order 4 means:

Each internal node can have max 3 keys and max 4 children.

Each leaf node can have max 3 entries.

All leaves are at the same level.

Internal nodes have at least ceil(m/2) children (so at least 2 children here, except root).

Leaf nodes contain actual data keys and are linked for fast sequential access.

When nodes overflow (exceed max keys), they split:

Leaf node splits into two leaves; the first key of the right leaf is promoted to the parent.

Internal node splits into two internal nodes; middle key promoted up.

The root can have fewer than minimum keys but must have at least two children if not a leaf. its a exa[le so you unsestand i can be any order user can out the oder also . so ifx it all
