# --description--
|
||||
|
||||
Given a sequence of integers, find a continuous subsequence which maximizes the sum of its elements, that is, the elements of no other single subsequence add up to a value larger than this one.
|
||||
|
||||
An empty subsequence is considered to have the sum of \\( 0 \\); thus if all elements are negative, the result must be the empty sequence.
|
||||
|
||||
# --hints--
|
||||
|
||||
`maximumSubsequence` should be a function.
|
||||
|
||||
```js
|
||||
assert(typeof maximumSubsequence == 'function');
|
||||
```
|
||||
|
||||
`maximumSubsequence([ 1, 2, -1, 3, 10, -10 ])` should return an array.
|
||||
|
||||
```js
|
||||
assert(Array.isArray(maximumSubsequence([1, 2, -1, 3, 10, -10])));
|
||||
```
|
||||
|
||||
`maximumSubsequence([ 1, 2, -1, 3, 10, -10 ])` should return `[ 1, 2, -1, 3, 10 ]`.
|
||||
|
||||
```js
|
||||
assert.deepEqual(maximumSubsequence([1, 2, -1, 3, 10, -10]), [1, 2, -1, 3, 10]);
|
||||
```
|
||||
|
||||
`maximumSubsequence([ 0, 8, 10, -2, -4, -1, -5, -3 ])` should return `[ 0, 8, 10 ]`.
|
||||
|
||||
```js
|
||||
assert.deepEqual(maximumSubsequence([0, 8, 10, -2, -4, -1, -5, -3]), [
|
||||
0,
|
||||
8,
|
||||
10
|
||||
]);
|
||||
```
|
||||
|
||||
`maximumSubsequence([ 9, 9, -10, 1 ])` should return `[ 9, 9 ]`.
|
||||
|
||||
```js
|
||||
assert.deepEqual(maximumSubsequence([9, 9, -10, 1]), [9, 9]);
|
||||
```
|
||||
|
||||
`maximumSubsequence([ 7, 1, -5, -3, -8, 1 ])` should return `[ 7, 1 ]`.
|
||||
|
||||
```js
|
||||
assert.deepEqual(maximumSubsequence([7, 1, -5, -3, -8, 1]), [7, 1]);
|
||||
```
|
||||
|
||||
`maximumSubsequence([ -3, 6, -1, 4, -4, -6 ])` should return `[ 6, -1, 4 ]`.
|
||||
|
||||
```js
|
||||
assert.deepEqual(maximumSubsequence([-3, 6, -1, 4, -4, -6]), [6, -1, 4]);
|
||||
```
|
||||
|
||||
`maximumSubsequence([ -1, -2, 3, 5, 6, -2, -1, 4, -4, 2, -1 ])` should return `[ 3, 5, 6, -2, -1, 4 ]`.
|
||||
|
||||
```js
|
||||
assert.deepEqual(maximumSubsequence([-1, -2, 3, 5, 6, -2, -1, 4, -4, 2, -1]), [
|
||||
3,
|
||||
5,
|
||||
6,
|
||||
-2,
|
||||
-1,
|
||||
4
|

]);
