Implement a prototype of a simple cache query handler that manages data entries stored in a cache. Each cache entry has the format: [timestamp, key, value]

The handler receives queries of the form: [key, timestamp]

For each query, you must return the corresponding data value stored in the cache for that exact [key, timestamp] pair.

Note:

• The same key can appear multiple times in the cache with different timestamps.
• For a given timestamp, a key is unique (no duplicate [timestamp, key] pairs).
• It is guaranteed that every queried [key, timestamp] exists in the cache.

You are given:

• cache_entries: a 2D array of strings, where each entry is [timestamp, key, value]
• queries: a 2D array of strings, where each query is [key, timestamp]

Return an array of integers representing the data values (converted from string to int) for each query.
