Fixed.

Hi,

the order of the given input and the instructions are different: "circular race track (km) and the time you run (h)" ≠ "time,round_length"

The Test description "test 2,1,1000,1000" may be more detailed. Example: "my_speed: 2, ghost_speed: 1, time: 1000, round_length: 1000"

Increased random tests to 100.

Fixed cases with missing points in the string "Cannot find Waldo."
When Waldo is missing, the text is still "Can not find Waldo.". If there are no objects around Waldo, you must return "Waldo is in the crowd."
Added test-case where Waldo is surrounded by people. Added random-tests where Waldo is missing.
The example test cases now contain every possible output (next to object, surrounded by people, Waldo missing).

Thanks for the feedback.

Fixed.

Random tests have been added. Array width and height vary individually.
Position of placed object around Waldo is random.
Possibility that there is no object around Waldo is also given.

Added the rule "There will not be more then one object next to Waldo."
