--description--

我们说如果其子串中的一个子串可被d整除则d位正数无前导零是一个子数。

例如5671是一个4位数的单子号码。在其所有子串5,6,7,1,56,67,71,567,671和5671中只有56可被4整除。类似地104是3位单子数因为只有0可被整除3. 1132451是一个7位数的单子号码因为只有245可被7整除。

设FN是小于N的一子数的数。我们可以验证F10= 9F103= 389和F107= 277674。

找到F1019

euler413()应该返回3079418648040719。

assert.strictEqual(euler413(), 3079418648040719);

function euler413() {

  return true;
