注意最后一页可能不够m个

注意最后一页可能不够m个就行了：

import java.util.*;
public class Main {
    public static void main(String[] args) throws Exception{
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        int[] v = new int[n];
        for(int i = 0; i < n; ++i) v[i] = sc.nextInt();
        int r = sc.nextInt(), m = sc.nextInt();
        if(r*m >= n){
            System.out.println("超过分页范围");
            return;
        }
        for(int i = r*m; i < Math.min(n, r*m + m); ++i){    //最后一页可能不够m个
            System.out.println(v[i]);
        }
    }
}
