This seems resolved now : "The second optional argument passes the minimum length. If your binary number is shorter than this length, then pad zeros on the left hand side to fulfill this minimum length ... "
I'm literally days in learning Ruby, and this simple solution has already taught me so much and made me think of so many more things that could be done with this concept, THANK YOU
According to the description, the second argument is the number of leading zeros, but the tests treat it as a full string length including other digits.
Use assert_equals
hahaha really cool solution :D
test_expect
...plus all the below issues
This comment is hidden because it contains spoiler information about the solution
to_s(2)
(see this)There should be some tests with the minimum width less than the number of digits. Random tests would be nice too.

Since it's explicitly mentioned in the description, there should be a test to check that
String#to_i(int)
isn't used.Needs random tests
Also base conversion is a duplicate
