/ you can write to stdout for debugging purposes, e.g.

 // printf("this is a debug message\n");

 #include <stdlib.h>

 }

 int solution(int A[], int N) {

     // write your code in C99

     // int len = sizeof(A)/sizeof(A[0]);

     // printf("%d len \n",len);

     qsort(A,N,sizeof(int),cmp);

     int i;

     for(i=;i<N-;i++)

     {

         // printf("%d \n",A[i]);

         if(A[i+]-A[i+]<A[i])

         {

             return ;

         }

     }

     return ;
