such that I have random access to all nodes at particular level of the

Like fast access to all nodes on level 3.

Methods for storing binary trees
Binary trees can be constructed from programming language primitives in
several ways. In a language with records and references, binary trees are
typically constructed by having a tree node structure which contains some
data and references to its left child and its right child. Sometimes it also
contains a reference to its unique parent. If a node has fewer than two
children, some of the child pointers may be set to a special null value, or
to a special sentinel
