You're right. I've changed the maximum number of random tests to 416. Thanks for the heads up.

I did what you said. Are the merge errors still present now?

I've modified the URL of Wikipedia site. Does the merge error exist?

Thanks for your suggestions.

I modified the assertion messages and made the assert_helper function accept two parameters (n and expected).

Answers:

• If n is greater than 417, the result will run into a u64 overflow error.
• Because n is smaller than 417, the solution of O(n²) doesn't take a long time.

I have removed the comment.

var _ = Describe("Test Example", func() {
  It("should test that the solution returns the correct value", func() {
      dotest(1, 1)
      dotest(2, 2)
      dotest(3, 3)
      dotest(4, 5)
      dotest(5, 7)
      dotest(10, 42)
  })
})

I have written the above tests in the sample test cases.
I'm new to CodeWars. Don't these tests count?

haha, it rocks.

The prime below 1000 with three prime permutations should include 136.

136 => 163, 613, 631

Do I say it right? I'm so confused.
