Description

Three arrays code, businessLine, and isActive (each of length n) describe n coupons. The i-th coupon has:

- code[i]: the coupon's identifier string.

- businessLine[i]: the coupon's business category.

- isActive[i]: whether the coupon is currently active.

A coupon is valid when all of the following hold:

- code[i] is non-empty and contains only alphanumeric characters or underscores (_).

- businessLine[i] is exactly one of "electronics", "grocery", "pharmacy", or "restaurant".

- isActive[i] is true.

Return the codes of all valid coupons sorted by businessLine in the order "electronics", "grocery", "pharmacy", "restaurant", then lexicographically within each category.
