This is based on coding?
Given that in a code language, '645' means 'day is warm;' '42' means 'warm spiring' and '634' means 'spring is sunny;' which digit represents 'sunny'?
The answer is 3. Could you please explain

645 - no "sunny" in that meaning, so we know that 6, 4 and 5 all do NOT mean "sunny"
42 - no "sunny" in that meaning, so we know that 4 and 2 do not mean "sunny"
we can add a third note here:
since 4 appears in both 645 and 42, and since the meaning "warm" also appears in both, we conclude that 4 means "warm"
This suggests that each digit stands for one word
and, indeed, what we see in the two example messages is: number of digits = number of words.
Therefore: in the message 634, 3 must mean "sunny"
