Question 1. Write a program to implement the Boyer-Moore algorithm. Your program should ask the user to enter a text and a pattern, then output the following: (a)  bad-symbol table   (b)  good suffix table  (c)  the searching result (whether the pattern is in the text or not)

Please make sure that the good suffix table is generated correctly. Use the following examples to test your program before submitting your assignment.

Examples:

Good suffix table for the pattern BAOBAB

k = 1   d2 = 2;     k = 2,   d2 = 5;     k = 3   d2 = 5;     k = 4   d2 = 5;      k = 5   d2 = 5

Good suffix table for the pattern AACCAC

k = 1   d2 = 2;     k = 2,   d2 = 3;     k = 3   d2 = 6;     k = 4   d2 = 6;      k = 5   d2 = 6

Good suffix table for the pattern AACCAA

k = 1   d2 = 1;     k = 2,   d2 = 4;     k = 3   d2 = 4;     k = 4   d2 = 4;      k = 5   d2 = 4

Good suffix table for the pattern 10000

k = 1   d2 = 3;     k = 2,   d2 = 2;     k = 3   d2 = 1;     k = 4   d2 = 5

Good suffix table for the pattern 01010

k = 1   d2 = 4;     k = 2,   d2 = 4;     k = 3   d2 = 2;     k = 4   d2 = 2

Question 2. Design a greedy algorithm to solve the activity selection problem. Suppose there are a set of activities: a₁, a₂, ... a_n that wish to use a lecture hall. Each activity a_i has a start time s_iand a finish time f_i. A lecture hall can be used by only one activity at a time. Two activities can be scheduled in the same lecture hall if they are nonconflicting (f_i<= s_j or f_j<= s_i) Your algorithm should find out the minimum number of lecture halls needed to hold all the activities. Write a program to implement your algorithm. For example: if the activities you need to schedule have the following start times and finish times,

4 7

6 9

7 8

1 3

1 4

2 5

3 7

then the output of your program is "the minimum number of lecture halls required is 3". Also indicate which activity will be scheduled in which lecture hall.
