An algorithm has been written in pseudocode to allow the names of 50 cities and their countries to be entered and stored in a two-dimensional (2D) array. The contents of the array are then output. 01 DECLARE City ARRAY[1:50, 1:2] OF BOOLEAN 02 DECLARE Count : INTEGER 03 DECLARE Out : INTEGER 04 Count ← 1 05 IF 06 OUTPUT "Enter the name of the city" 07 INPUT City[Count, 2] 08 OUTPUT "Enter the name of the country" 09 INPUT City[Count, 2] 10 Count← Count + 1 11 UNTIL Count = 50 12 FOR Out ← 1 TO 1 13 OUTPUT "The city ", City[Out, 1], " is in ", City[Out, 2] 14 NEXT Out
