| Given a generic tuple type `T extends unknown[]`, write a type which produces all permutations of `T` as a union. | ||
|
|
||
| For example: | ||
|
|
||
| ```ts | ||
| PermutationsOfTuple<[1, number, unknown]> | ||
| /** | ||
| * Should return: | ||
| * | [1, number, unknown] | ||
| * | [1, unknown, number] | ||
| * | [number, 1, unknown] | ||
| * | [unknown, 1, number] | ||
| * | [number, unknown, 1] | ||
| * | [unknown, number ,1] | ||
| */ | ||
| ``` | ||
|
|
||
|
|
||
| // Should return: | ||
| // | [1, number, unknown] | ||
| // | [1, unknown, number] | ||
| // | [number, 1, unknown] | ||
| // | [unknown, 1, number] | ||
| // | [number, unknown, 1] | ||
| // | [unknown, number ,1] | ||
| ``` | ||
