(In reply to computer lists possibilities; logic narrows down to actual answers
In reading broll's solution, I see I inadvertently assumed that the "country with a lesser population" was also a European country, though the puzzle did not necessarily indicate that. So that leaves Algeria and Armenia in contention.
Algeria has a 40.61 million population according to Wikipedia.
Armenia has a 2.925 million population.
Croatia has 4.171 million.
Romania has 19.71 million.
Austria has 8.787 million.
I had Romania and Austria.
It could have been Romania and Armenia or Croatia and Armenia.
Added: Croatia's capital is (Z)agreb and Armenia's is (Y)erevan.
