Consider a digital electric circuit operating with binary signals in a discrete time. It contains input signals, wires, junctions and logical gates. We will use six kinds of logical gates: NOT, AND, NAND, OR, NOR, DFF. Each of them returns one output signal. The amount of input signals and details about return value are showed in the following table.

Gate	Inputs	Return value
NOT	1	Opposite to the input signal value.
AND	1 or more	Conjunction of the input signal values.
NAND	1 or more	Negation of the conjunction of the input signal values.
OR	1 or more	Disjunction of the input signal values.
NOR	1 or more	Negation of the disjunction of the input signal values.
DFF	1	Same as the input signal. Returned with the delay of one tick of discrete time.

The scheme will operate in the following manner. Before the first tick of the discret time each DFF gate is initialized with zero value. Then during certain amount of ticks several junctions ( junctions) will be feeded with input values. You are to write a program that will calculate binary values on a certain set of junctions ( junctions).

Your program will be given the description of the logical scheme, the set of junctions in which we are interested and the input values for each consecutive tick of the discrete time.

The input file consists of two blocks. First block contains several lines. If the first symbol of a line is a sharp "#", than the line contains a comment. You can ignore it. You can also ignore empty lines. A line describing the input signal looks like

INPUT(junction)

, where

junction

is the name of the junction. A line describing the interesting junction looks like

OUTPUT(junction)

, where

junction

is the name of the junction. A junction name consists of small and capital Latin letters and digits and the underline character "_". The length of each name is less than 64 characters.

All other lines of the first block contain the description of new junctions. Such line can look like

j1 = op(j2)

, where

j1

and

j2

are the names of junctions and

op

is either

NOT

or

DFF

. It can also look like

j1 = op(j2[, j3...])

, where

j

's are the junction names and

op

is

AND

,

NAND

,

OR

or

NOR

. There will be no more than 5 · 10³ junctions.

The second block of the input file starts with the line

INPUT VALUES

. Each of the following lines contains a sequence of zeroes and ones. Amount of digits equals to the amount of input signals. You should match these binary values to the input signal values, in the order the input signals given. There are no more than 500 lines in this block. Please refer to the sample for the details.

The input file size is less than 320 KB.

You may assume that the input data is correct. You may assume that the given circuit will operate correctly.

For each line of the input signal values, print one line containing zeroes and ones. The digits should correspond to the values of the output signals, preserving their order in the input file.
