Today’s Agenda Problem Solving
Problem statement • Consider an employee database. It stores the information of employees in some organization. It maintains idno, name, salary and division of each employee. This information is stored in a file input.txt. Also number of employees is mentioned in the file on the first line of the file. • Salary is divided into different ranges • Less than 10,000 • 10,000 to 25,000 • 25,000 to 40,000 • 40,000 to 55,000 • More that 55,000
Separate the employee details based on their salary into different lists. • Store the list of employees into different files.

Problem IV (revisiting) • Declare two sequential lists using singly linked list. Populate data (numbers) in both the list by insert operation. • Perform merging of two list. Maintain increasing order of numbers in the resultant list. • Merge two list and create a new list. • Without creating a new list modify the links of the two lists and create a new list. Such merging is called in-place merging.
