不知道哪里有错,WA到快失去信心了

#include<stdio.h>
#include<stdlib.h>
#include<string.h>

int cmp(const void *a,const void *b)
{
    return(*(int *)b-*(int *)a);
}
int main()
{

    int inpt[10000],flag[10000];
    int other[10000];
    int peo,ncard,i,count=0;
    while(scanf("%d %d",&peo,&ncard)!=EOF)
    {
        if(peo==0 && ncard==0)
            break;
        memset(flag,0,sizeof(flag));
        memset(other,0,sizeof(other));
        memset(inpt,0,sizeof(inpt));
        int maxpip;
        maxpip=peo*ncard;
        for(i=0;i<ncard;i++)
        {
            scanf("%d",&inpt[i]);
            flag[inpt[i]]=1;
        }
        for(i=1;i<=maxpip;i++)
        {
            if(flag[i]==0)
            {
                other[i]=i;
            }
        }
        qsort(inpt,ncard,sizeof(inpt[0]),cmp);
        qsort(other,maxpip,sizeof(other[0]),cmp);
        int k=0,j=0,gain=0;
        while(k!=ncard)
        {
            if(inpt[k]>other[j])
            {
                gain++;
                k++;
            }
            else
            {
                k++;
                j++;
            }
        }
        printf("Case %d: %d\n",++count,gain);
    }
    return 0;
}
