Function<String, String> fun = (String fullName) -> fullName.split("\s")[1]; We create aFunctionwhich is a key extractor. It extracts the surnmaes from the strings. names.sort(Comparator.comparing(fun).reversed()); We pass the function to theComparator.comparingmethod. $ java Main.ja...
A student's record consists of his or her distinct ID (a 6-digit number), name (a string with no more than 8 characters without space), and grade (an integer between 0 and 100, inclusive). Output Specification: For each test case, output the sorting result in N lines. That is, if...

key 默认是 None,即恒等函数(identity function),也就是默认用元素自己的值排序。 举栗子: >>> list_a = ['This', 'is', 'a', 'test', 'string', 'from', 'Andrew'] >>> sorted(list_a, key=str.lower) ['a', 'Andrew', 'from', 'is', 'string', 'test', 'This'] >>> list_a ...
Here we focus on using Radix Sort to sort integers, but it’s not limited to just numbers.We can use it to sort other types such asString,too. In order to keep it simple, we’re gonna focus on the decimal system in which the numbers are expressed in base (radix) 10. ...
