c语言代码解决问题

解题思路:

注意事项:

参考代码:

#include<stdio.h>

#include<stdlib.h>

int main()

{

    int m,n,a[100]={0}, * b,i,j,flag,sum=0;

    scanf("%d %d", &m, &n);

    b = (int*)malloc(sizeof(int) * n);

    for (i = 0; i < n; i++)

        scanf("%d", &b[i]);

    for (i = 0; i < n; i++)

    {

        flag = 0;

        for (j = 0; j < m; j++)

        {

            if (b[i] == a[j])

            {

                flag = 1;

                break;

            }

        }

        if (!flag)

        {

            sum++;

            for (j = m; j >= 1; j--)

            {

                a[j] = a[j - 1];

            }

            a[0] = b[i];

        }

    }

    printf("%d", sum);

    return 0;
