Description

It is possible to write five as a sum in exactly six different ways:

4 + 1
3 + 2
3 + 1 + 1
2 + 2 + 1
2 + 1 + 1 + 1
1 + 1 + 1 + 1 + 1

How many different ways can one hundred be written as a sum of at least two positive integers?

Instructions

Tests

tests:
  - text: <code>countingSummations()</code> should return a number.
    testString: assert(typeof countingSummations() === 'number');
  - text: <code>countingSummations()</code> should return 190569291.
    testString: assert.strictEqual(countingSummations(), 190569291);

Challenge Seed

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

countingSummations();
