An array represents the status of a sequence of 7 weather sensors along a mountain trail. Each sensor can be either active (A) or idle (I).

Subroutine	Explanation
`INVERT(n)`	If the sensor at index $n$ is `A`, it is set to `I`. If it is `I`, it is set to `A`.
`COPY_LST(n)`	The sensor at index $n$ is set to the same status as the sensor at index ( $n - 1$ ).
`RESET_RANGE(m, n)`	All sensors between index $m$ and index $n$ (but not including $m$ and $n$ ) are set to `I`.

0	1	2	3	4	5	6
I	A	A	I	A	I	I

What will the array of sensors become after the following algorithm is executed?

p ← 2
INVERT(p + 2)
COPY_LST(p - 1)
INVERT(p + 1)

Write your final answer in the table below:

0	1	2	3	4	5	6
