Assignment B

Q1: Case Study

Bubble sort is a simple sorting algorithm. It works by repeatedly stepping through the list to be sorted, comparing each pair of adjacent items and swapping them if they are in the wrong order. The pass through the list is repeated until no swaps are needed, which indicates that the list is sorted. The algorithm gets its name from the way smaller elements “bubble” to the top of the list. Because it only uses comparisons to operate on elements, it is a comparison sort.

a)         Consider the following values sorted in an array. Sort it in ascending order using Bubble sort technique showing all the iterations:

15, 43, 5, 18, 27, 3,10

b)         Also write a C function to sort one dimensional integer array in ascending order using Bubble Sort technique.

Q2) .Assume that you have two build two different Data structures based on the clients requirements:

■       One client is running a school and requires storing student information in a sequential manner, which data structure do you use, write an outline diagram for it.

■       Next client is a cinema theatre owner and would prefer to fill in seats as and when customers come to hall, mention the data structure preferred and represent it diagrammatically.

Q3): What do you mean by a Graph? How graphs are represented? Explain

Q4). Explain the theory of Minimum spanning trees.
