Flatten Array in Objective-C
Take a nested list and return a single list with all values except nil/null
exercism fetch objective-c flatten-array
Take a nested list and return a single flattened list with all values except nil/null.
The challenge is to write a function that accepts an arbitrarily-deep nested list-like structure and returns a flattened structure without any nil/null values.
There are two different methods of getting set up to run the tests with Objective-C:
- Create an Xcode project with a test target which will run the tests.
- Use the ruby gem
objcas a test runner utility.
Both are described in more detail here: http://exercism.io/languages/objective-c
When submitting an exercise, make sure your solution file is in the same directory as the test code.
The submit command will look something like:
exercism submit <path-to-exercism-workspace>/objective-c/flatten-array/FlattenArray.m
You can find the Exercism workspace by running
exercism debug and looking for the line beginning
