答案

type TwoSum<T extends number[], U extends number> = any

验证

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

type cases = [
  Expect<Equal<TwoSum<[3, 3], 6>, true>>,
  Expect<Equal<TwoSum<[3, 2, 4], 6>, true>>,
  Expect<Equal<TwoSum<[2, 7, 11, 15], 15>, false>>,
  Expect<Equal<TwoSum<[2, 7, 11, 15], 9>, true>>,
  Expect<Equal<TwoSum<[1, 2, 3], 0>, false>>,
  Expect<Equal<TwoSum<[1, 2, 3], 1>, false>>,
  Expect<Equal<TwoSum<[1, 2, 3], 2>, false>>,
  Expect<Equal<TwoSum<[1, 2, 3], 3>, true>>,
  Expect<Equal<TwoSum<[1, 2, 3], 4>, true>>,
  Expect<Equal<TwoSum<[1, 2, 3], 5>, true>>,
  Expect<Equal<TwoSum<[1, 2, 3], 6>, false>>,
  Expect<Equal<TwoSum<[3, 2, 0], 2>, true>>,
]
