Given an array A[a1,a2,a3,...an] of size n. Create an array B[] from A[] where b1=a1,b2=a1+a2,b3=a1+a2+a3, bn=a1+a2+a3+...+an. (Java or c++)

   public static void main(String[] args) {

       int A[] = {1,2,3,4};

       int B[] = new int[A.length];

       for (int x = 0; x < A.length; x++){

           if (x == 0){

               B[x] = A[x];

           }

           else{

               B[x] = B[x-1] + A[x];

           }

       }

       for (int w:B){

           System.out.println(w);

       }

   }

}

I created my solution in java. I hope this helps!

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).

continuous information you receive.
