--description--

Let T(m, n) be the number of the binomial coefficients iCn that are divisible by 10 for n ≤ i < m(i, m and n are positive integers).

You are given that T(109, 107-10) = 989697000.

Find T(1018, 1012-10).

--hints--

euler322()应该返回999998760323314000。

assert.strictEqual(euler322(), 999998760323314000);
