A Common-Sense Guide to Data Structures and Algorithms, Second Edition - exercises with `array.sort` (page 476)
In the answers for the Chapter 13 exercises, there are several uses of JavaScript’s array.sort() to sort an array of numbers. However, this sorts numbers as strings, and so a number like 22 will appear before a number like 3:
[3, 1, 22].sort();
// [ 1, 22, 3 ], when what we want is [ 1, 3, 22 ]
The answers should replace uses of array.sort() with:
array.sort((a, b) => (a < b) ? -1 : 1);
