What is the various ways to print the contents of a hash?

Hash in Perl is nothing but an associative array i.e. Each key is associate with its value and can be displayed using either key or value. It is preferred over simpler array because instead of printing value based on index number, you can print by using key.

  1. $hash{'key'} = 'value';

We will discuss Hash fundamentals in another tutorial where I will explain everything which is required to understand hash clearly with some examples. Let’s see here, how we can display the contents of hash. We assume we have a hash defined as %hash = (some key value pairs);

Google Wants to Eliminate Search
The search engine giant Google always has something up its sleeve. At times the company is introducing new and fun gadgets and some times it is researching on how to build robots. But the company really wants to take a step back and look at the basics for a while especially its search facility. Google is not just experimenting this time – it is serious. The experts at Google want to eliminate the one thing that Google does best – searching.
There is nothing to worry about because the company intends to introduce semantic searching which, to them, makes more sense. The company has provided that when users usually search for something, all the related search results appear on the page. The user has to quickly glance at all the results before clicking on the one that is the most relevant. This is what Google is not happy about.
