poj1007我的代码为什么会错？
上代码：

C/C++ code

#include<iostream>#include<cstdio>#include<cstdlib>using namespace std;struct counts{    int id;    int count;};int compare(const void *a, const void *b){    counts *num1, *num2;    num1=(counts *)a;    num2=(counts *)b;    return num1->count-num2->count;}int main(){    int n, m;    scanf("%d %d", &n, &m);        counts *c=new counts[m];    char **seq=new char *[m];    for(int i=0; i<m; ++i){        seq[i]=new char[n+1];    }        for(int i=0; i<m; ++i){        scanf("%s", seq[i]);        c[i].id=i;        c[i].count=0;        for(int j=0; j<n; ++j){            for(int k=j+1; k<n; ++k){                if(seq[i][k]-seq[i][j]<0){                    c[i].count+=seq[i][j]-seq[i][k];                }            }        }    }    qsort(c, m, sizeof(counts), compare);        for(int i=0; i<m; ++i){        printf("%s\n", seq[c[i].id]);    }    return 0;}

顺便附原题啊：http://poj.org/problem?id=1007

[解决办法]
计算count那行和题目的意思有偏差吧，我认为是+1
