Peak power month of a region
A grid operator plans maintenance outside the busiest month of each region. Monthly consumption is stored in energy.csv for 2024 and 2025.
month: YYYY-MMregion: region name (for example Iberia or US Midwest)mwh: electricity consumed that month in megawatt-hours (whole number)
Task: the first input line is a region (exactly as in the file), the second line a year such as 2025. Print two lines: Total MWh: T (sum over that region and year) and Peak month: M (V MWh) where M is the month with the highest consumption and V its value. If two months tie, print the earlier one. If there is no data, print No data on a single line instead.
