Define a class Employee for employees, create N objects of Employee, sort these objects and search, the specific requirements are as follows. Fields of Employee at least include name, ID, department, salary, birthday. Create N (N>10000) objects of Employee, and the values of instance variables for these objects should be different. a) b) Sort these Employee objects with InsertionSort and Quicksort by name and birthday, print the first 10 objects' fields to check if the results are correct, and record the times costed by these sortings in table 1. You need ensure that different algorithms have the same input data sequence. InsertionSort Quicksort Table 1 Performances of sorting N lists Binary search trees or AVL trees Hash tables Costed time By name d) Search for employees by name and age respectively, and different data structures should be used to store Employee objects before searching, including lists, binary search trees or AVL trees, hash tables. Record the times spent on sorting in table 1. You need ensure that different algorithms have the same input data sequence.
