Display the monthly (12 months) snowfall records for the city that have the longest snow season (most months have snowfall).

Display the monthly (12 months) temperature for the hottest city (one record is enough, no need for the solution for tie) and the coldest city (different curve/line) in one plot graph.

Display the average of temperature, # of sunny days, and # of rainy days in each month (3 curves/lines) in United States in one plot graph.

Display the monthly (12 months) temperature for the hottest city (one record is enough, no need for the solution for tie) in summer (June, July, & August) and the coldest city in winter (December, January, and February) in one plot graph (2 curves).

Display the monthly (12 months) temperature for the top 5 hotest cities that have the average (year) temperature in 50’s (>= 50 and <60) in one plot graph (five curves).

What is X? What is Y? What is Z?

Make your own X, Y Determine the corresponding Z

Find the distance from (i, j) to (dx(1), dy(1)), the first city in record. min_d2 = (dx(1)-(i-1+minx))*(dx(1)-(i-1+minx)) + (dy(1)-(j- 1+miny))*(dy(1)-(j-1+miny)); Set the current closest city index => 1 st id = 1; Find the kth city from city2 to the city_num-th city in the record ◦ Check the distance from (i,j) to (dx(k), dy(k)) if it can beat the record min_d2 ◦ If yes, update id=k update z(j,i) = dz(id);
