int n,i;
int odd,even;
odd=even=0;
int a[] = new int[100];
System.out.println("Enter the number of elements");
n= Integer.parseInt(s.readLine());
System.out.println("Enter the "+n+" numbers");
for(i=0;i<n;i++)
 {
  a[i]=Integer.parseInt(s.readLine());
  if(a[i]%2==0)
    {
    even++;
    }
  else
    {
        odd++;
    }
  }
System.out.println("Odd numbers are:" +odd);
