Read the scenario (Pickerings Properties).
(a) List the functions of the system, as perceived by an external user.
(b) List the external entities. Note that because we are modelling the data flows, not use cases, the external entities should be the actual sources and sinks of data rather than the persons keying in the data.
(c) Produce a context (or level 0) data flow diagram using the method described in the unit materials.
Deletion Algorithm for dequeue Step 1: [check for underflow] If front = 0 and rear = 0 Output "underflow" and return Step 2: [delete element at front end] If front
The number of different directed trees with 3 nodes are ?? The number of disimilar directed trees with three nodes are 3
Q. Prove the hypothesis that "A tree having 'm' nodes has exactly (m-1) branches". Ans: A tree having m number of nodes has exactly (m-1) branches Proof: A root
Assertions and Abstract Data Types Even though we have defined assertions in terms of programs, notion can be extended to abstract data types (which are mathematical entities).
Definition: A set of data values & related operations that are accurately specified independent of any particular implementation. As the data values and operations are described
Thus far, we have been considering sorting depend on single keys. However, in real life applications, we may desire to sort the data on several keys. The simplest instance is that

A useful tool which is used for specifying the logical properties of a data type is called the abstract data type or ADT. The term "abstract data type" refers to the fundamental ma
