Fill the World Map by Bordering Country Pairs by Combined Maximum Height
Type the names of the two bordering countries where the sum of their maximum heights is greatest. Remove those two countries from the map and keep going! Country A comes before B in alphabetical order!
h = maximum height of Country A + maximum height of Country B, in metres
Overseas borders are considered
Highlighted rows indicate that Country A and Country B have the same maximum height
Hint: start with the two countries sharing the highest mountain in the world!
