Algorithm常用函数（3）

18. 移除特定元素——remove

 1 #include<cstdio>
 2 #include<iostream>
 3 #include<cstring>
 4 
 5 //remove
 6 #include<algorithm>
 7 #include<numeric>
 8 using namespace std;
 9 
10 int main()
11 {
12 int all[11] = {11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1};
13 int *a = remove(all, all + 11, 2);// 移除all中所有数值为2的元素
14 
15 for(int i = 0 ; i < a - all ; i ++)
16 printf_s("%d	", all[i]);
17 
18 return 0;
19 }

19. 交换——swap

 1 #include<cstdio>
 2 #include<iostream>
 3 #include<cstring>
 4 
 5 //swap
 6 #include<algorithm>
 7 #include<numeric>
 8 
 9 using namespace std;
10 
11 int main()
12 {
13     int all[11] = {11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1};
14 
15     swap(all[0], all[1]);//交换两个位置元素
16 
17     for(int i = 0 ; i < 11 ; i ++)
18         printf_s("%d	", all[i]);
19 
20     return 0;
21 }

20. 移除重复元素——unique

 1 #include<cstdio>
 2 #include<iostream>
 3 #include<cstring>
 4 
 5 #include<algorithm>
 6 #include<numeric>
 7 using namespace std;
 8 
 9 int main()
10 {
11     int all[11] = {11, 10, 9, 9, 7, 7, 5, 4, 3, 1, 1};
12 
13     int *a = unique(all, all + 11);//移除所有重复元素
14 
15     for(int i = 0 ; i < a - all; i ++)
16         printf_s("%d	", all[i]);
17 }
