Argusoft 2nd round programming questions with solution

program 2- write a program to input some number and check whether it belongs to series-1 or not.

series 1 :- 4,2,5,20,40,200,4000,160000,32000000

Solution

#include<stdio.h>

#define N 9

int input[N];

void main()

{

                int i,j,k,l;

                printf("Predefined series is 4,2,5,20,40,200,4000.....\n");

                printf("Enter number Minimum 9 numbers of the series to check\n");

                for(i=0;i<N;i++)

                {

                                scanf("%d",&input[i]);

                }

               //series goes like this 1*3=4

               //2*4=5

               //3*5=6

                int check;

                j=0;

                k=2;

                l=3;

                for(i=0;i<N;i++)

                {

                                if(input[j++]*input[k++]==input[l++])

                                check=1;

                                else

                                check=0;

                                if(l==N-1)

                                break;

                }

                if(check)

                printf("\nInputted series belongs to predefined series");

                else

                                printf("\nInputted series not belongs to predefined series");

}
