The accompanying file weather.dat contains weather data for a single month as space-separated values. The first column (Dy) contains the day of the month; the second (MxT) contains the maximum temperature for that day, while the third (MnT) contains the minimum temperature.
The final row contains aggregate values for the entire month.
Write a program to find the row with the maximum spread in the weather.dat file, where spread is defined as the difference between MxT and MnT. For example, the spread for day 2 was (79 - 63) = 16.
Your program should print the day of the month and spread to standard output.
Assuming that your program is called weather.py, then a sample run will look like:
$ python weather.py
2 16
… where 2 is the day of the month with the maximum spread, and the actual spread is 16. (The actual day and spread will depend on the contents of the file.)
- You may code your solution in any language (if you are comfortable with Python, that's a good way to go)
- You are not allowed to edit the weather.dat file before running your program on it.
- Include a readme.txt file explaining how to run your code, and detailing any assumptions you have made.
- Focus on producing a correct and efficient solution with well-organized, readable code.
