Get Parent Category Id in Sub Category Page - Magento

Question

I need a small line of code. I have a category like

• Cat-1
  • Sub-Cat-1
  • Sub-Cat-2
• Cat-2
  • Sub-Cat-3
  • Sub-Cat-4

In Sub-Cats page i need to get Root category's Id. Like In "Sub-Cat-1" i need to get "Cat-1's" ID. You can say in children category page, i need parent category's Id. act i am using short url like "abc.com/Sub-Cat-1", nither index.php nor root category in URL. I am using Magento-1.4.1. Please help me. Thanks in advance.
