Question

Write a user-defined function EXTRA_ELE(int A[ ], int B[ ], int N) in C++ to find and display the extra element in Array A. Array A contains all the elements of array B but one more element extra. (Restriction: array elements are not in order)

Example If the elements of Array A is 14, 21, 5, 19, 8, 4, 23, 11 and the elements of Array B is 23, 8, 19, 4, 14, 11, 5 Then output will be 21

Answer 1

The function is as follows:

void EXTRA_ELE(int A[ ], int B[ ], int N)

{

  int i,j, flag =0;

  for (i=0;i<N; i++)

  {

      for (j=0; j<N;j++)

       {

          if (A[i]== B[j])

             {

                 flag=1;

                 break;

             }

       }

       if(lag==0)

                  count<<"extra element"<<A[i];

   flag=0;

  }

}

Like this N displays 3,15,6,18,12,9.
