How to Solve Closest Room Problem

There is a hotel with n rooms. The rooms are represented by a 2D integer array rooms where rooms[i] = [roomIdi, sizei] denotes that there is a room with room number roomIdi and size equal to sizei. Each roomIdi is guaranteed to be unique. You are also given k queries in a 2D array queries where queries[j] = [preferredj, minSizej]. The answer to the jth query is the room number id of a room such that: If there is a tie in the absolute difference, then use the room with the smallest such id. If there is no such room, the answer is -1. Return an array answer of length k where answer[j] contains the answer to the jth query.
