Chapter 9: Problem 15

To sort N numbers, bubble sort continues making passes through the array until _______.

Short Answer

Expert verified
Answer: The bubble sort algorithm stops making passes through the array when no swaps are needed in a complete pass, indicating that the array is already sorted.

Step by step solution

01

Understand the Bubble Sort Algorithm

The bubble sort algorithm compares each pair of adjacent elements in an array and swaps them if they are in the wrong order. This is done repeatedly until the algorithm has made a complete pass through the array without having to make any swaps, which indicates that the array is sorted.
02

Recognize the Stopping Condition

The stopping condition for the bubble sort algorithm is when it has made a complete pass through the array without having to make any swaps. This means that, during a pass, if no elements were swapped, the algorithm stops because the array is already sorted. Hence, the bubble sort continues making passes through the array until no swaps are needed in a complete pass.

If an array is sorted in ________ order, the values are stored from lowest to highest.

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

Which sort, bubble sort or selection sort, would require fewer passes to sort a set of data that is already in the desired order?

Assume an array of structures is in order by the customerID field of the record, where customer IDs go from 101 to 500 . A) Write the most efficient pseudocode algorithm you can to find the record with a specific customerID if every single customer ID from 101 to 500 is used and the array has 400 elements. B) Write the most efficient pseudocode algorithm you can to find a record with a customer ID near the end of the IDs, say \(494,\) if not every single customer ID in the range of 101 to 500 is used and the array size is only 300 .

Bubble sort places ________ number(s) in place on each pass through the data.
