You shouldn't use parentheses without a purpose

Sure. I have changed the description and examples to reflect your suggestions. Thanks for your contribution!

Would you be interested in some edited language in the descriptions so other's don't make the same mistake as I did? For example: given a pattern and a string str, find if str follows the same sequence as pattern.

The examples, as written, can be taken two different ways also, so maybe something like:
word_pattern('abab', 'truck car truck car') == true

word_pattern('aaaa', 'dog dog dog dog') == true

word_pattern('abab', 'apple banana banana apple') == false

word_pattern('aaaa', 'cat cat dog cat') == false

Hi ecocode

There is only one number test and that is in the Initial Tests section. For the random tests, all the strings are chars.

hello and thanks for this kata, i am enjoying it BUT!! i keep failing one test. Is it possible for the pattern to contain at least one element that is a number greater than 9?
Thank you.

Haha I see it now. Thanks for your patience!

Ok I must be completely mistaken about how the kata should be working. I thought the string should include the letter in the pattern? Truck does not include the letter b. In the other examples this holds true and is what I was trying to achieve.

I need to know why you think your solution should pass. Why is your solution returning false? For pattern abba and str car truck truck car, you can see that a = car and b = truck. So a(car)b(truck)b(truck)a(car). Your solution should return true

I was working through the ruby version. If you need more info than that let me know what you need.

I need more info than that man.

This is one of the test cases: Test.assert_equals(word_pattern('abba', 'car truck truck car'), true)

I was wondering why I kept failing the tests.

It's still confusing. I used

n.to_i    

and most test cases passed, integer or not, but the random input test cases failed. I can just change the code based on your comment above but still don't understand what's expected.
