There are various types of sort algorithms defined in Java that are useful based on the complexity of the structure. Below is the code block that defines overriding the comparator interface to give our implementation for sorting the elements. import java.util.*; public class DepartmentComparator {...

Here we need to define our user-defined comparator function to do the above thing. Like we will take each element of the 2D vector (which is a 1D vector, to be specific each row) and compare based on the first element (or any particular element) only. That's why we need auser-defi...

This binary predicate takes two arguments and returns true if the two arguments are in order and false otherwise. This comparator function must impose a strict weak ordering on pairs of elements from the sequence. For more information, see Algorithms. Remarks The range referenced must be valid; ...
void sort ( void * base , size_t num , size_t size , int ( * comparator ) ( const void * , const void * ) ) sort 函数接受四个参数,第一个参数是要操作的数组,第二个参数 是数组的大小,第三个参数是数组中每个元素的大小,第四个参数 是一个比较函数,它有两个参数,比较函数返回值小于 0...
