 # Ruby Practice
 
-Run your Ruby file by typing `ruby ` and then the name of the file you want to run in the Terminal.
-
-If we want to run `hash_person.rb`, we can write the command:
-
-```bash
-ruby hash_person.rb
-```
-
-To re-run this command, you can use the UP and DOWN arrow keys to look at the history of commands you've run in a Terminal.
-
-## Hash
-
-### hash_person.rb
-Input:
-```
-Maude 24 Artist
-```
-
-Key output:
-`{ :name => "Maude", :age => 24, :occupation => "Artist" }`
-
-Complete input and output example:
-```bash
-"Enter a name, age, and occupation separated by spaces:"
-Maude 24 Artist
-{ :name => "Maude", :age => 24, :occupation => "Artist" }
-```
-
-###### Make sure the value of the :age key is an Integer
-
-### hash_dig.rb
-
-Write a program that uses the `sample_hash` variable and prints the value of key "history"
-
-```ruby
-sample_hash = {
-   :class => { 
-      :student => { 
-         :name => "Mike",
-         "marks" => { 
-            "physics" => 70,
-            "history" => 80
-         }
-      }
-   }
-}
-```
-
-### hash_find_value.rb
-
-Write a program that:
-   Asks the user for an Integer, then checks to see if that integer is
-   a value of any of the keys in sample_hash.
-   If you find the number, print out "100 is under the key: a."
-   If you don't find the number print out "Could not find the integer 100"
-
-Example:
-
-```bash
-"Enter an integer:"
-4
-"Could not find the integer 4"
-```
-
-### hash_list.rb
-
-Given this list of people, print only names of people who are at least 16.
-
-Yes, you could just look at it with your eyes and print their names, but imagine that you couldn't because there are a million items in the list.
-
-Use the variable, loops, and conditionals instead.
-
-Output something like:
-
-```bash
-"Jerry"
-"Sloane"
-"Hurly"
-```

-## Specs
-<details>

-
-hash_person.rb prints Hash of '{:name => "Osi", :age => 24, :occupation => "Songwriter"}', when input is 'Osi 24 Songwriter' 
-
-hash_person.rb prints Hash of '{:name => "Lia", :age => 32, :occupation => "Engineer"}', when input is 'Lia 32 Engineer' 
-
-hash_find_value.rb prints Hash of 'Could not find the integer 4', when input is '4' 
-
-hash_find_value.rb prints Hash of '100 is under the key: a.', when input is '100' 
-
-hash_find_value.rb prints Hash of '22 is under the key: e.', when input is '22' 
-
-hash_find_value.rb prints Hash of '32 is under the key: e.', when input is '32' 
-
-hash_dig.rb prints '80' by retriving the value from the Hash 
-
-hash_list.rb prints 'James', 'Yolanda', 'Red', and  'Fatimah' using variables, loops, if statements, and Hash methods'
