I find what's wrong with my code in the above post.
In comp() for qsort(C language) I can not use

Code: Select all

int comp(double *p,double *q)
{ 
    return  *q-*p;
}
I should use

Code: Select all

int comp(double *p,double *q)
{ 
    if(*q-*p>0) return 1;   
    else if(*q-*p<0) return -1;   
    else return 0;
}
By the way, I have a wonder: Why can't we break the loop when I find a solution. Is it not the biggest area?
