When the search is unsuccessful, we attempt to insert the new element into the last internal node encountered on the search path. If such an element is found, The insert fails because duplicates are not permitted.
To insert an element into a B-tree we first search for the presence of an element with the same key.
Here m =7 m/2 =7/2 =3.5 =4 figure 2 Insertion into a B tree All external nodes are at the same level. The elements are ordered so that k1 External nodes B trees of order mĭefinition A B-tree in Data Structures at sizzler in is an m-way search tree if the B-tree is not empty, The corresponding extended tree satisfies the following properties The root has at least two children Fill internal nodes other than the root have at least children. In the corresponding extended search Tree, each inter-node has up to in children and between 1 and m-1 elements (External nodes contain no elements and have no children) Every node with p elements has exactly p+1 children Consider any node with p elements. An m-way search tree may be empty if it is not empty it is a tree that satisfies The following properties
