生成随机int数组方法（数据未知）
#include "iostream"
#include "time.h"
using namespace std;
int *RandomInit(int range, int count)//给定range数据取值范围，count数组大小
{
int *num = new int(count);
int local;
srand(time(0));
for (int i = 0; i < count; i++)
{
num[i] = (rand() * i) % range;
}
for (int i = count; i > 0; i--)
{
local = rand() % i;
if (i - 1 == local)
continue;
num[i - 1] += num[local];
num[local] = num[i - 1] - num[local];
num[i - 1] = num[i - 1] - num[local];
}
return num;
}
生成随机Int序列(给定数据)
#include "iostream"
#include "time.h"
#include "vector"
using namespace std;
void RandomList(vector<int> &num)
{
int local;
srand(time(0));
for (int i = num.size(); i > 0; i--)
{
local = rand() % i;
if (i - 1 == local)
continue;
num[i - 1] += num[local];
num[local] = num[i - 1] - num[local];
num[i - 1] = num[i - 1] - num[local];
}
}
生成随机序列（给定数据）--模板函数
#include "iostream"
#include "time.h"
#include "vector"
using namespace std;
template <class T>
void RandomList(vector<T> &list)
{
int local;
T tmp;
srand(time(0));
for (int i = list.size(); i > 0; i--)
{
local = rand() % i;
if (i - 1 == local)
continue;
tmp = list[local];//因为不确定类型，只能用三元交换法.
list[local] = list[i - 1];
list[i - 1] = tmp;
}
}
