int n=Integer.parseInt(num);
int arr[]= new int[n];
System.out.println("Enter the values of the array not more then "+n+".");
for(int i=0;i<n;i++)
{
num=obj.readLine();
arr[i]=Integer.parseInt(num);
}
System.out.println("ARRAY-->");
for(int i=0;i<n;i++)
System.out.print(arr[i]+" ");
int t;
int a=0, b=n-1;
while(a<b && a!=b)
{
t=arr[b];
arr[b]=arr[a];
arr[a]=t;
a++;
b--;
