--description--
通过列出前六个素数:2,3,5,7,11和13,我们可以看到第6个素数是13.第n
个素数是多少?
--hints--
nthPrime(6)
应该返回13。
assert.strictEqual(nthPrime(6), 13);
nthPrime(10)
应该返回29。
assert.strictEqual(nthPrime(10), 29);
nthPrime(100)
应该返回541。
assert.strictEqual(nthPrime(100), 541);
nthPrime(1000)
应该返回7919。
assert.strictEqual(nthPrime(1000), 7919);
nthPrime(10001)
应该返回104743。
assert.strictEqual(nthPrime(10001), 104743);
