#define N  10000
#include"stdio.h"

long x,y;
long z;
long n,i,j;

main()
{      scanf("%d",&n);
       for(i=0;i<n;i++)
       {   scanf("%ld%ld",&x,&y);
           z=y-x;
           for(j=1;j<z;j++)
            {  x=x+j;
               if(x>=(y-1)) 
                  { printf("%d\n",j+1);break;}
             }
         }
}
我为什么错呢？
