It contain a data field, a pointer to the left and a pointer to the right child. Btree reduces the number of disk reads by allowing more keys in a single node typically making a btree node as large as. Leaking means not calling free to dispose of memory that was malloced during runtime before exiting the program. A binary search tree is a binary tree in symmetric order. The left, right and father fields of a node point to the nodes left son, right son and father respectively.
