This should be relatively concise. It turns out that it is an interval of the numbers in the m-1 segment. This idea is very interesting:

/*ID: qq104801LANG: C++TASK: barn1*/#include <stdio.h>#include <stdlib.h>#include <string.h>#include <assert.h>/* for debug only:counter*/void debug_dummy(void){    return;}int m,s,c;int bb[200],cc[200];int cmpa(const void *a,const void *b){    return *(int*)a - *(int*)b;}int cmpd(const void *a,const void *b){    return *(int*)b - *(int*)a;}int test(void){    int total,i;        if(m>=s)       return c;    else   {            cc[0]=0;                for(i=1;i<c;i++)            cc[i]=bb[i]-bb[i-1]-1;        qsort(cc,c,sizeof(cc[0]),cmpd);        //for(i=0;i<c;i++)            //printf("%d\n",cc[i]);        total=bb[i-1]-bb[0]+1;        //printf("%d\n",total);       for(int i=0;i<m-1;i++)                   total-=cc[i];                  }   return total;    }main () {        FILE *fin = fopen ("barn1.in", "r");    FILE *fout = fopen ("barn1.out", "w");     fscanf(fin,"%d %d %d",&m,&s,&c);    for(int i=0;i<c;i++)    {        fscanf(fin,"%d",&bb[i]);    }    qsort(bb,c,sizeof(bb[0]),cmpa);    int count=0;    count=test();    //printf("%d\n",count);    fprintf(fout,"%d\n",count);        fclose(fin);    fclose(fout);    exit (0);}
