--description--

对于任何正整数n第n个弱Goodstein序列{g1g2g3...}定义为g1 = n对于k> 1gk是通过在基k中写gk-1获得的将其解释为a基数k + 1减去1。

当gk变为0时序列终止。

例如第6个弱Goodstein序列是{6,11,17,25...}g1 = 6. g2 = 11因为6 = 1102,1103 = 1212 - 1 = 11. g3 = 17 11 = 1023,1024 = 18,18-1 = 17.g4 = 25因为17 = 1014,1015 = 26,26-1 = 25。

等等。

可以证明每个弱的Goodstein序列都会终止。

设Gn为第n个弱Goodstein序列中的非零元素的数量。可以证实G2= 3G4= 21和G6= 381.还可以证实ΣGn= 25171≤n<8。

找到ΣGn的最后9位数1≤n<16。

--hints--

euler396()应该返回173214653。

assert.strictEqual(euler396(), 173214653);

--seed--

--seed-contents--

function euler396() {

  return true;
}

euler396();
