# --description--
|
||||
|
||||
An infinite sequence of real numbers a(n) is defined for all integers n as follows:
|
||||
|
||||
<!-- TODO Use MathJax and re-write from projecteuler.net -->
|
||||
|
||||
For example,a(0) = 11! + 12! + 13! + ... = e − 1 a(1) = e − 11! + 12! + 13! + ... = 2e − 3 a(2) = 2e − 31! + e − 12! + 13! + ... = 72 e − 6
|
||||
|
||||
with e = 2.7182818... being Euler's constant.
|
||||
|
||||
It can be shown that a(n) is of the form
|
||||
|
||||
A(n) e + B(n)n! for integers A(n) and B(n).
|
||||
|
||||
For example a(10) =
|
||||
|
||||
328161643 e − 65269448610!.
|
||||
|
||||
Find A(109) + B(109) and give your answer mod 77 777 777.

# --hints--

`euler330()` should return 15955822.
|
||||
|
||||
```js
|
||||
assert.strictEqual(euler330(), 15955822);
|
||||
```

|
