Compute Pascal's triangle up to a given number of rows.
In Pascal's Triangle each number is computed by adding the numbers to the right and left of the current position in the previous row.
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
# ... etc
Execute the tests with:
$ mix testIn the test suites, all but the first test have been skipped.
Once you get a test passing, you can unskip the next one by
commenting out the relevant @tag :pending with a # symbol.
For example:
# @tag :pending
test "shouting" do
assert Bob.hey("WATCH OUT!") == "Whoa, chill out!"
endOr, you can enable all the tests by commenting out the
ExUnit.configure line in the test suite.
# ExUnit.configure exclude: :pending, trace: trueIf you're stuck on something, it may help to look at some of the available resources out there where answers might be found.
