title: 'Problem 322: Binomial coefficients divisible by 10'
---

## Description
<section id='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).
