--description--

For non-negative integers m, n, the Ackermann function A(m, n) is defined as follows:

A(m, n) = \begin{cases} n + 1 & \text{if $m = 0$} \\\\ A(m - 1, 1) & \text{if $m > 0$ and $n = 0$} \\\\ A(m - 1, A(m, n - 1)) & \text{if $m > 0$ and $n > 0$} \end{cases}

For example A(1, 0) = 2, A(2, 2) = 7 and A(3, 4) = 125.

Find \displaystyle\sum_{n = 0}^6 A(n, n) and give your answer mod {14}^8.

--hints--

ackermanFunction() should return 1098988351.

assert.strictEqual(ackermanFunction(), 1098988351);
