AI solution for TypeScript puzzle on BFE.dev
36. implement LargerThan<A, B>
Here is one possible solution:
type LargerThan<A extends number, B extends number> = A extends B ? false : ( B extends A ? true : LargerThan<A extends 0 ? 0 : A-1, B extends 0 ? 0 : B-1>);
Explanation:
- The type
LargerThan<A, B>
compares two non-negative integersA
andB
. - If
A
is equal toB
, then the result isfalse
. - If
B
is smaller thanA
, then the result istrue
. - Otherwise, we recursively call
LargerThan
withA-1
andB-1
.
Note:
- We need to handle the special case when
A
orB
is zero, because TypeScript does not support negative numeric types. - This solution uses recursion, which may not be the most efficient way to solve the problem. However, for small values of
A
andB
, it should work fine.
