解题思路

待补充

答案

type FindEles<T extends any[]> = any

验证

import type { Equal, Expect } from '@type-challenges/utils'

type cases = [
  Expect<Equal<FindEles<[1, 2, 2, 3, 3, 4, 5, 6, 6, 6]>, [1, 4, 5]>>,
  Expect<Equal<FindEles<[2, 2, 3, 3, 6, 6, 6]>, []>>,
  Expect<Equal<FindEles<[1, 2, 3]>, [1, 2, 3]>>,
  Expect<Equal<FindEles<[1, 2, number]>, [1, 2, number]>>,
  Expect<Equal<FindEles<[1, 2, number, number]>, [1, 2]>>,
]
