Description

A sequence is defined as:

gk = 1, for 0 ≤ k ≤ 1999 gk = gk-2000 + gk-1999, for k ≥ 2000. Find gk mod 20092010 for k = 1018.

Instructions

Tests

tests:
  - text: <code>euler258()</code> should return 12747994.
    testString: assert.strictEqual(euler258(), 12747994, '<code>euler258()</code> should return 12747994.');

Challenge Seed

function euler258() {
  // Good luck!
  return true;
}

euler258();
