Question

Parvati is given an array of integers. She is asked to return the sum of all the two-digit numbers in the array. Please help her to perform this task. Write a function: class Solution { public int solution (int[] A); } that, given an array A consisting of N integers, returns the sum of all two-digit numbers. For example, given A = [1, 1000, 80, -91], the function should return -11 (as the two-digit numbers are 80 and -91). Given A = [47, 1900, 1, 90, 45], the function should return 182 (as the two-digit numbers are 47, 90 and 45). Given A = [-13, 1900, 1, 100, 45), the function should return 32 (as the two-digit numbers are -13 and 45). Assume that: • N is an integer within the range [0..100,000); • each element of array A is an integer within the range [-2,147,483,648..2,147,483,647]. In your solution, focus on correctness. The performance of your solution will not be the focus of the assessment.

code:

import java.util.*;
class Solution
{
   public static void main(String args[])
   {
       int A[]=new int[10000];
       int N;
       System.out.println("Enter n value(array size):");
       Scanner s=new Scanner(System.in);
       N=s.nextInt();
       System.out.println("Enter array values:");
       for(int i=0;i<N;i++)
       {
           A[i]=s.nextInt();
       }
       System.out.println("---------------------");
       System.out.println(solution(A));
   }
   public static int solution(int A[])
   {
       int sum=0;
       for(int i=0;i<A.length;i++)
       {
           if((A[i]>10 && A[i]<100)||(A[i]<(-10)&&A[i]>(-100)))
           {
               sum+=A[i];
           }
       }
       return sum;
   }
}
  
------------------------------------

output:

C:\Users\meghasyam\Documents\subjects>javac Solution.java

C:\Users\meghasyam\Documents\subjects>java Solution
Enter n value(array size):
5
Enter array values:
47

C:\Users\Documents\subjects>javac Solution.java

C:\Users\Documents\subjects>java Solution
Enter n value(array size):

---------------------------------

this will perform well.

Thankyou.
