+ * Generates a random integer between the specified minimum and maximum values, inclusive.
+ *
+ * The expression `Math.floor(Math.random() * (maximum - minimum + 1)) + minimum` works as follows:
+ * 1. `Math.random()` generates a floating-point number in the range [0, 1).
+ * 2. Multiplying by `(maximum - minimum + 1)` scales this to the range [0, maximum - minimum + 1).
+ * 3. `Math.floor()` rounds the result down to the nearest integer, giving a value in [0, maximum - minimum].
+ * 4. Adding `minimum` shifts the range to [minimum, maximum].
+ *
+ * As a result, `num` will be a random integer between `minimum` and `maximum`, inclusive.
