12. Given a File of N employee records with a set K of Keys (4-digit) which uniquely determine
the records in file F. Assume that file F is maintained in memory by a Hash Table (HT) of m
memory locations with L as the set of memory addresses (2-digit) of locations in HT. Let the
keys in K and addresses in L are Integers. Design and develop a Program in C that uses Hash
function H: K →L as H(K)=K mod m (remainder method), and implement hashing
technique to map a given key K to the address space L. Resolve the collision (if any) using
linear probing.
Laboratory Outcomes: The student should be able to:
• Analyze and Compare various linear and non-linear data structures
• Code, debug and demonstrate the working nature of different types of data structures and their
applications
• Implement, analyze and evaluate the searching and sorting algorithms
• Choose the appropriate data structure for solving real world problems
Conduct of Practical Examination:
• Experiment distribution
- For laboratories having only one part: Students are allowed to pick one experiment from
the lot with equal opportunity. - For laboratories having PART A and PART B: Students are allowed to pick one
experiment from PART A and one experiment from PART B, with equal opportunity.
• Change of experiment is allowed only once and marks allotted for procedure to be made zero of
the changed part only.
• Marks Distribution (Courseed to change in accoradance with university regulations)
c) For laboratories having only one part – Procedure + Execution + Viva-Voce: 15+70+15 =
100 Marks
d) For laboratories having PART A and PART B
i. Part A – Procedure + Execution + Viva = 6 + 28 + 6 = 40 Marks
ii. Part B – Procedure + Execution + Viva = 9 + 42 + 9 = 60 Marks
