|

The series, 1<sup>1</sup> + 2<sup>2</sup> + 3<sup>3</sup> + ... + 10<sup>10</sup> = 10405071317.
|
||||
|
||||
Find the last ten digits of the series, 1<sup>1</sup> + 2<sup>2</sup> + 3<sup>3</sup> + ... + 1000<sup>1000</sup>.

# --hints--
|

|
||||
`selfPowers(10, 3)` should return a number.
|
||||
|
||||
```js
|
||||
assert(typeof selfPowers(10, 3) === 'number');
|
||||
```
|
||||
|
||||
`selfPowers(10, 3)` should return 317.
|
||||
|
||||
```js
|
||||
assert.strictEqual(selfPowers(10, 3), 317);
|
||||
```
|
||||
|
||||
`selfPowers(150, 6)` should return 29045.
|
||||
|
||||
```js
|
||||
assert.strictEqual(selfPowers(150, 6), 29045);
|
||||
```
|
||||
|
||||
`selfPowers(673, 7)` should return 2473989.
|
||||
|
||||
```js
|
||||
assert.strictEqual(selfPowers(673, 7), 2473989);
|
||||
```
|
||||
|
||||
`selfPowers(1000, 10)` should return 9110846700.
|
||||
|
||||
```js
|
||||
assert.strictEqual(selfPowers(1000, 10), 9110846700);
|
