Rising Temperature Visualizer & Solution

id
2
4

Let's walk through the example:

For id=1 (2015-01-01, 10), there is no previous day to compare, so it's excluded.
For id=2 (2015-01-02, 25), the previous day was 2015-01-01 with a temperature of 10. Since 25 > 10, id=2 is included in the result.
For id=3 (2015-01-03, 20), the previous day was 2015-01-02 with a temperature of 25. Since 20 is not greater than 25, id=3 is excluded.
For id=4 (2015-01-04, 30), the previous day was 2015-01-03 with a temperature of 20. Since 30 > 20, id=4 is included in the result.

Therefore, the final output contains ids 2 and 4.

Therefore, the final output contains ids 2 and 4.
