Explanation:

Test case 11: The initial population of the town was 33 million, out of which 11 million people left and 22 million people entered the town. So, final population = 3 – 1 + 2 = 4=3−1+2=4 million.

Test case 22: The initial population of the town was 22 million, out of which 22 million left and 22 million immigrated. The final population is thus 2+2-2 = 22+2−2=2 million.
