--description--
If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.
Find the sum of all the multiples of 3 or 5 below the provided parameter value number
.
--hints--
multiplesOf3and5(10)
should return a number.
assert(typeof multiplesOf3and5(10) === 'number');
multiplesOf3and5(49)
should return 543.
assert.strictEqual(multiplesOf3and5(49), 543);
multiplesOf3and5(1000)
should return 233168.
assert.strictEqual(multiplesOf3and5(1000), 233168);
multiplesOf3and5(8456)
should return 16687353.
assert.strictEqual(multiplesOf3and5(8456), 16687353);
multiplesOf3and5(19564)
should return 89301183.
assert.strictEqual(multiplesOf3and5(19564), 89301183);
