AP - Complete The Series v2

 Link to the question : AP3

HINT :

Again a simple question based on the arithmetic progression. The problem becomes tricky if not taken care of the precisions.

RECOMMENDED QUESTION :

Try your hands on this question .

SOURCE CODE :

#include<stdio.h>

#include<math.h>



int main()

{

    int t; scanf("%d",&t);

    while(t--)

    {

       long long int a3,a3l,s,i,a,d,len;  

           

      long double n,sq,diff;

      scanf("%lld",&a3); 

      scanf("%lld",&a3l);

      scanf("%lld",&s);

      

      sq=sqrtl(((5.0*a3l+7.0*a3+2.0*s)*(5.0*a3l+7.0*a3+2.0*s))-(48.0*(a3l+a3)*s));

      n=((5.0*a3l+7.0*a3+2.0*s)+sq)/(2.0*(a3l+a3));

      

      len=llrintl(n);

      printf("%lld\n",len);

      

      diff=(a3l-a3)/(len-6.0);

      d=llrintl(diff);

      

      a=(a3-(2*d));

       for(i=0;i<len;i++)

       {

                       printf("%lld ",a+i*d);

       }

        printf("\n");

       

       

       }   

      

     return 0;
