## Description
给定一个整数序列，找到一个连续的子序列，它最大化其元素的总和，也就是说，没有其他单个子序列的元素加起来大于这一个的值。空子序列被认为具有\（0 \）的总和;因此，如果所有元素都是负数，则结果必须是空序列。
## Instructions
## Tests
```yml
tests:
- text: maximumSubsequence应该是一个函数。
testString: 'assert(typeof maximumSubsequence=="function","maximumSubsequence should be a function.");'
- text: 'maximumSubsequence("+JSON.stringify(tests[0])+")应该返回一个数组。'
testString: 'assert(Array.isArray(maximumSubsequence(tests[0])),"maximumSubsequence("+JSON.stringify(tests[0])+") should return an array.");'
- text: 'maximumSubsequence("+JSON.stringify(tests[0])+")应返回"+JSON.stringify(results[0])+" 。'
testString: 'assert.deepEqual(maximumSubsequence(tests[0]),results[0],"maximumSubsequence("+JSON.stringify(tests[0])+") should return "+JSON.stringify(results[0])+".");'
- text: 'maximumSubsequence("+JSON.stringify(tests[1])+")应返回"+JSON.stringify(results[1])+" 。'
testString: 'assert.deepEqual(maximumSubsequence(tests[1]),results[1],"maximumSubsequence("+JSON.stringify(tests[1])+") should return "+JSON.stringify(results[1])+".");'
- text: 'maximumSubsequence("+JSON.stringify(tests[2])+")应返回"+JSON.stringify(results[2])+" 。'
testString: 'assert.deepEqual(maximumSubsequence(tests[2]),results[2],"maximumSubsequence("+JSON.stringify(tests[2])+") should return "+JSON.stringify(results[2])+".");'
- text: 'maximumSubsequence("+JSON.stringify(tests[3])+")应返回"+JSON.stringify(results[3])+" 。'
testString: 'assert.deepEqual(maximumSubsequence(tests[3]),results[3],"maximumSubsequence("+JSON.stringify(tests[3])+") should return "+JSON.stringify(results[3])+".");'
- text: 'maximumSubsequence("+JSON.stringify(tests[4])+")应返回"+JSON.stringify(results[4])+" 。'
testString: 'assert.deepEqual(maximumSubsequence(tests[4]),results[4],"maximumSubsequence("+JSON.stringify(tests[4])+") should return "+JSON.stringify(results[4])+".");'
- text: 'maximumSubsequence("+JSON.stringify(tests[5])+")应返回"+JSON.stringify(results[5])+" 。'
testString: 'assert.deepEqual(maximumSubsequence(tests[5]),results[5],"maximumSubsequence("+JSON.stringify(tests[5])+") should return "+JSON.stringify(results[5])+".");'
```
## Challenge Seed
```js
function maximumSubsequence (population) {
// Good luck!
}
```
### After Test
```js
console.info('after the test');
```
## Solution
