* chore: remove old formatter

* fix: update getChallenges

parse translated challenges separately, without reference to the source

* chore(curriculum): add dashedName to English

* chore(curriculum): add dashedName to Chinese

--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。

--hints--

maximumSubsequence应该是一个函数。

assert(typeof maximumSubsequence == 'function');

maximumSubsequence("+JSON.stringify(tests[0])+")应该返回一个数组。

assert(Array.isArray(maximumSubsequence([1, 2, -1, 3, 10, -10])));

maximumSubsequence("+JSON.stringify(tests[0])+")应返回"+JSON.stringify(results[0])+" 。

assert.deepEqual(maximumSubsequence([1, 2, -1, 3, 10, -10]), [1, 2, -1, 3, 10]);

maximumSubsequence("+JSON.stringify(tests[1])+")应返回"+JSON.stringify(results[1])+" 。

assert.deepEqual(maximumSubsequence([0, 8, 10, -2, -4, -1, -5, -3]), [
  0,
  8,
  10
]);

maximumSubsequence("+JSON.stringify(tests[2])+")应返回"+JSON.stringify(results[2])+" 。

assert.deepEqual(maximumSubsequence([9, 9, -10, 1]), [9, 9]);

maximumSubsequence("+JSON.stringify(tests[3])+")应返回"+JSON.stringify(results[3])+" 。

assert.deepEqual(maximumSubsequence([7, 1, -5, -3, -8, 1]), [7, 1]);

maximumSubsequence("+JSON.stringify(tests[4])+")应返回"+JSON.stringify(results[4])+" 。

assert.deepEqual(maximumSubsequence([-3, 6, -1, 4, -4, -6]), [6, -1, 4]);

maximumSubsequence("+JSON.stringify(tests[5])+")应返回"+JSON.stringify(results[5])+" 。

assert.deepEqual(maximumSubsequence([-1, -2, 3, 5, 6, -2, -1, 4, -4, 2, -1]), [
  3,
  5,
  6,
  -2,
