Chapter 9: Problem 1

The ___________ search algorithm steps sequentially through an array, comparing each item with the search value.

Short Answer

Expert verified
Explain the process of a sequential search algorithm, and how it operates when searching for a given value in an array.

Step by step solution

01

Understand the problem

We have an array of elements and a search value. The task is to find the search value in the array using the sequential search algorithm.
02

Set up the initial conditions

Start at the beginning of the array, i.e., set the index variable i to 0.
03

Compare the search value with the current array element

Compare the search value with the array element at index i (array[i]).
04

Check for a match

If the search value is equal to array[i], then we have found a match, and the search can be terminated.
05

Move to the next element

If the search value does not match the current element, increment the index variable i by 1 to move to the next element in the array.
06

Check if the end of the array has been reached

If the index variable i is equal to or greater than the length of the array, then the search value is not present in the array, and the search can be terminated.
07

Repeat steps 3 to 6

Continue repeating steps 3 to 6 until either a match is found or the end of the array has been reached.
08

Return the result

If a match was found in step 4, return the index i at which the match occurred; otherwise, return a value indicating that the search value was not found in the array, typically -1.

Why is selection sort more efficient than bubble sort on large arrays?

Assume that empName and empID are two parallel arrays of size numBmp that hold employee data. Write a pseudocode algorithm that sorts the emp ID array in ascending ID number order (using any sort you wish), such that the two arrays remain parallel. That is, after sorting, for all indexes in the arrays, empName [index] must still be the name of the employee whose ID is in empID [Index].

The____________ search algorithm repeatedly divides the portion of an array being searched in half.

The maximum number of comparisons performed by linear search to find an item in an array of N elements is ___________.

Team up with two to three other students and jointly decide how you would organize, order, and locate the data used in the following application. Be prepared to present your group's design to the rest of the class. The program to be developed is a menu-driven program that will keep track of parking tickets issued by the village that is hiring you. When a ticket is issued the program must be able to accept and store the following information: ticket number, officer number, vehicle license plate state and number, location, violation code (this indicates which parking law was violated), and date and time written. The program must store information on the amount of the fine associated with each violation code. When a ticket is paid the program must be able to accept and store the information that it has been paid, the amount of the payment, and the date the payment was received. The program must be able to accept inquiries such as displaying the entire ticket record when a ticket number is entered. The program must also be able to produce the following reports: A list of all tickets issued on a specific date, ordered by ticket number A list of all tickets for which payment was received on a specific date and the total amount of money collected that day A report of all tickets issued in a one-month period, ordered by officer number, with a count of how many tickets each officer wrote A report of all tickets that have not yet been paid, or for which payment received was less than payment due, ordered by vehicle license number
