Write the method evaluateLight
, which computes and returns the status of a light at a given row and column based on the following rules.
- If the light is on, return
false
if the number of lights in its column that are on is even, including the current light. - If the light is off, return
true
if the number of lights in its column that are on is divisible by three. - Otherwise, return the light’s current status.
For example, suppose that LightBoard sim = new LightBoard(7, 5)
creates a light board with the initial state shown below, where true
represents a light that is on and false
represents a light that is off. Lights that are off are shaded.
Note:
This assignment does not have an autograder! Use the LightBoardTester
method to compare the results of evaluateLight
to the lightboard that is created from the constructor.
