Q1
a) Data structures are two of basic types. Explain the 2 types and site 2 examples of each (6mks)
b) For an algorithm to be qualified as efficient and fast, 2 conditions must hold true. Describe them (4mks)
c) Best case time complexity or the best amount of time and algorithm can possibly take to complete should be measured. How is it achieved? (2mks)
d) Explain the following terminologies associated with a tree structure:
• Root
• Leaf
• Traversing
(3mks)
e) Represent the two operations of a queue data structure with the aid of a well labeled diagram (5mks)

Q2
a) Space complexity property of algorithms is vital in multiuser systems and situations where limited memory is available. What 3 components of space complexity must be addressed? (6mks)
b) What would be your guideline as a programmer when considering several types of data structures (2mks)
c) For any queue operation there must be supporting functions to ensure efficiency.
