How many integers can I create in 1 GB of memory?

Question

Robert Sedgewick’s fourth edition of Book Algorithms on page 200 says: “For example, if you have 1 GB of memory on your computer (1 billion bytes), you cannot store more than 32 million int values.”

I was confused after my calculations: 1,000,000,000 bytes / 4 bytes = 250 million

How did the author get 32 ​​million?

The book describes as shown below:

Answer 1

The author acknowledged that this is a mistake on this website of the book, please refer to the following link: http://algs4.cs.princeton.edu/errata/errata-printing3.php

Answer 2

1 gigabit = 1073741824 bit
1 int = 32 bits
calculation = (1073741824/32) = (32 * 1024 ² ) = (32 * 2 ²⁰ ) = 32 million

If the author meant giga bytes , then the answer would be (32 * 8) million = 256 million
