Refactor — Name Parser with LET

An HR analyst's "split full name into first/last" pair of formulas calls FIND(" ", A2) three times across the two cells:

B2 (First): =LEFT(A2, FIND(" ", A2)-1)
C2 (Last):  =MID(A2, FIND(" ", A2)+1, LEN(A2)-FIND(" ", A2))

The space position is computed three times per row across the two formulas. LET binds it once per cell:

B2: =LET(s, FIND(" ", A2), LEFT(A2, s-1))
C2: =LET(s, FIND(" ", A2), MID(A2, s+1, LEN(A2)-s))

The win is mostly readability — s is named, the formula reads top-to-bottom, and FIND happens once per cell instead of two/three times.

The data at A2:A13 has 12 full names (single space between first and last, no middle names).

Your task:

1. In column B (First Name), write a LET-based formula that returns just the first name.
2. In column C (Last Name), write a LET-based formula that returns just the last name.
3. Both formulas must drag-fill from row 2 → row 13.

Graded cells: B3 (Bree Lin → Bree), C6 (Eli Brooks → Brooks), B10 (Ivy Wood → Ivy).
