Question 10
Let $N$ be the number of ways to write $2010$ in the form $$
\begin{aligned} 2010 &= a_3 \cdot 10^3 + a_2 \cdot 10^2 \\ &\quad {}+ a_1 \cdot 10 + a_0, \end{aligned}
$$ where the $a_i$’s are integers, and $0 \le a_i \le 99.$ An example of such a representation is $1 \cdot 10^3$ $+ 3 \cdot 10^2$ $+ 67 \cdot 10^1$ $+ 40 \cdot 10^0.$ Find $N.$
