Weather Data Summary

You are given a JSON array representing the weather statistics of consecutive days. Each element in the array is a JSON object containing the following fields:

• date (a string representing the date, e.g. "2023-01-01")
• temperature (a number representing the temperature on that day)
• humidity (an integer representing the humidity percentage)
• wind_speed (a number representing the wind speed)

Your task is to compute a summary of the weather data with the following outputs:

• The average temperature over all days (rounded to two decimals).
• The date on which the humidity was highest (if there are ties, choose the first occurrence in the array).
• The total wind speed accumulated over all days (rounded to one decimal place).
</p>

Note: The input is provided via stdin as a JSON string and your output should be printed to stdout in JSON format.

inputFormat

The input is a single JSON array (read from standard input) where each element is a JSON object with the following keys: date (string), temperature (number), humidity (integer) and wind_speed (number). You can assume that the array contains at least one element.

outputFormat

The output should be a JSON object (printed to standard output) containing the following keys:

• average_temperature: the average of all temperatures rounded to two decimals (in LaTeX: \(\text{average} = \round(\frac{\sum temperature}{n}, 2)\)).
• highest_humidity_day: the date corresponding to the highest humidity.
• total_wind_speed: the sum of all wind speeds rounded to one decimal place (in LaTeX: \(\text{total} = \round(\sum wind\_speed, 1)\)).
