Java的泛型是什么呢, 就是类型的参数化,也就是原本该是确定类型的地方换成了变量,把类型的确定时间向后延迟了。
在之前,学过“重载”的概念,重载是什么呢,举例来说
public class Test{
// 处理整型数据
void receive(int i) {
System.out.println("Received one int data");
System.ou...

方法一 使用strsplit函数
a <- "aggcacggaaaaacgggaataacggaggaggacttggcacggcattacacggagg"
b <- strsplit(as.character(a),"ag")
length(b[[1]]) - 1 ##子字符串"ag"的出现个数
方法二 使用正则式函数
a <- "aggcacgg...

冒泡排序
思路:就是每次将最大或最小的元素放到数组的最后,so easy!时间复杂度为(O(n^2))
public class BubbleSort {
public static void bubbleSort(int[] a) {

使用函数操作链表
1:计算链表中结点的个数:定义一个Length_list()函数用于计算链表中结点的个数
函数代码:
//计算链表中结点的个数
void Length_list(PNODE pHead)
{
PNODE p = pHead->pNext;
int len = 0;
while(NULL != p)
{
len++;
p = p->pNext;
