What is the difference between a Hash and an Array? +A hash is a collection of key-value pairs that can be accessed by unique keys. An array is a collection that is accessed by numeric index. 2. When would you use an Array over a Hash and vice versa? +An array can access its elements instanenously by its index. If a particular object needs to be access by a key value, for example by name, then a Hash collection who's key is a name string would be ideal. Arrays are useful as stacks or queues. Hash's are useful when you need rapid access by arbitrary keys. 3. What is a module? Enumerable is a built in Ruby module, what is it? +A module is a way to provide a namespace for a group of methods, classes, and constants. As a namspace, a module helps prevent collisions with other unrelated but similary named methods, classes, and constants. A module also lets you mixin module methods into classes. + +The Enumerable module defines methods that iterate over collections, such as map, include?, find_all?. One can define their own collection class by defining an iterator method called 'each' which returns elements in the collection. That class may include or 'mixin' the Enumerator module and the new collection class now has all the standard Enumerable methods. 4. Can you inherit more than one thing in Ruby? How could you get around this problem? + No, a class can only inherit from a single base class. You can, however, mixin as many modules as you want within a class. 5. What is the difference between a Module and a Class? + A module just defines a namespace and grouping of a set of methods, classes, and constants. A class defines a type of object. A class can be instaniated into an object, modules cannot. Classes can inherit from other classes, modules cannot. A module can be included in classes and other modules. \ No newline at end of file diff --git a/week2/homework/simon_says.rb b/week2/homework/simon_says.rb new file mode 100644 index 0000000..29f3305 --- /dev/null +++ b/week2/homework/simon_says.rb @@ -0,0 +1,23 @@ +module SimonSays + + def echo(word) + word + end + + def shout(word) + word.upcase + end + + def repeat(word, count = 2) + ((word + " ") * count).rstrip + end + + def start_of_word(word, count) + word[0, count] + end + + def first_word(sentence) + sentence.split(" ").first + end + +end \ No newline at end of file From 67418e40ba8648165d180e01010e4bf91049e173 Mon Sep 17 00:00:00 2001 From: Tom Underhill Date: Sun, 19 Oct 2014 11:54:19 -0700 Subject: [PATCH 04/15] Finished week 3 homework --- week3/homework/calculator.rb | 36 ++++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 week3/homework/calculator.rb diff --git a/week3/homework/calculator.rb b/week3/homework/calculator.rb new file mode 100644 index 0000000..cd9fa9c --- /dev/null +++ b/week3/homework/calculator.rb @@ -0,0 +1,36 @@ +class Calculator + + def pow power, number + p = 1 + number.times { p *= power } + p + end + + def sum array + s = 0 + array.each do |value| + s += value + end + s + end + + def multiply numOrArray, num = 0 + m = 1 + if numOrArray.class == Array + numOrArray.each do |value| + m *= value + end + else + m = numOrArray * num + end + m + end + + def fac n + f = 1 + (1..n).each do |a| + f *= a + end + f + end +end From 117dbda1b35e28aacbee3cd73fb33e69d75f45ad Mon Sep 17 00:00:00 2001 From: Tom Underhill Date: Sun, 19 Oct 2014 11:55:28 -0700 Subject: [PATCH 05/15] Week 3 homework --- week3/homework/calculator.rb | 31 ++++++++++++++++++++++++++++++- week3/homework/questions.txt | 9 +++++++++ 2 files changed, 39 insertions(+), 1 deletion(-) diff --git a/week3/homework/calculator.rb b/week3/homework/calculator.rb index cd9fa9c..9fdb30a 100644 --- a/week3/homework/calculator.rb +++ b/week3/homework/calculator.rb @@ -14,7 +14,36 @@ def sum array s end - def multiply numOrArray, num = 0 + def multiply *args + if args[0].class == Array + multiplyArray args[0] + else + multiplyArray args + end + end + + def multiplyArray array + m = 1 + array.each do |value| + m *= value + end + m + end + + def multiply_Alternative *args + if args[0].class == Array + array = args[0] + else + array = args + end + m = 1 + array.each do |value| + m *= value + end + m + end + + def multiply_Alternative2 numOrArray, num = 0 m = 1 if numOrArray.class == Array numOrArray.each do |value| diff --git a/week3/homework/questions.txt b/week3/homework/questions.txt index dfb158d..77c33c3 100644 --- a/week3/homework/questions.txt +++ b/week3/homework/questions.txt @@ -5,11 +5,20 @@ Please Read: - Chapter 22 The Ruby Language: basic types (symbols), variables and constants 1.
