1/*2  730 - Union to Tuple3  -------4  by Sg (@suica) #hard #union #tuple #infer5  6  ### Question7  8  Implement a type, `UnionToTuple`, that converts a union to a tuple.9  10  As we know, union is an unordered structure, but tuple is an ordered, which implies that we are not supposed to preassume any order will be preserved between terms of one union, when unions are created or transformed. 11  12  Hence in this challenge, **any permutation of the elements in the output tuple is acceptable**.13  14  Your type should resolve to one of the following two types, but ***NOT*** a union of them!15  ```ts16  UnionToTuple<1>           // [1], and correct17  UnionToTuple<'any' | 'a'> // ['any','a'], and correct18  ```19  or 20  ```ts21  UnionToTuple<'any' | 'a'> // ['a','any'], and correct22  ```23  It shouldn't be a union of all acceptable tuples...24  ```ts25  UnionToTuple<'any' | 'a'> // ['a','any'] | ['any','a'], which is incorrect26  ```27  28  29  And a union could collapes, which means some types could absorb (or be absorbed by) others and there is no way to prevent this absorption.
