and numbered consecutively starting from
1. Each of the LED lights is

initially in its

operations, a left and right index will be
provided. When a current is applied to two
LED lights, a NOT operation is applied to
each LED light in the inclusive interval
between those lights. That is, if a light is
OFF, it is turned ON, and vice versa. Given a
series of operations, determine their final
