## Description

Jessie was learning about programming contests at Bessie's knee.
"Do they play games?" she asked.
"Oh yes," Bessie nodded sagely. "Here's a classic."
MasterMind is a classic two player game. One of the players is the
'codemaker'; she picks a four digit secret number S (1000 <= S <=
9999). The other player is the 'codebreaker' who repeatedly guesses
four digit numbers until she solves the code.
The codemaker provides feedback that comprises two integers for
each codebreaker guess G_i (1000 <= G_i <= 9999). For each codebreaker
guess, the codemaker's feedback comprises two integers:
* The first integer C_i (0 <= C_i <= 4) specifies how many of the
guess's digits are correct and in their correct location in the
secret number
* The second integer W_i (0 <= W_i <= 4-C_i) specifies how many of
the remaining digits (i.e., those not described by C_i) are correct
but in the wrong location.
For example, suppose codemaker's secret number is 2351. If codebreaker
guesses 1350, the codemaker provides the feedback "2 1", since 3
and 5 are in correct locations in the number, and 1 is in the wrong
location. As another example, if the secret number is 11223 (in a
five-digit version of mastermind) and the guess is 12322, then the
feedback would be "2 2".
Below is a sample game where the secret number is 2351:
Correct digits in correct location
| Correct digits in wrong location
Guess | |
3157 1 2
1350 2 1
6120 0 2
2381 3 0
2351 4 0
For this task, you are given N (1 <= N <= 100) guesses with their
feedback in the middle of a game. You are asked to output the
smallest four digit number which can be a candidate for codemaker's
secret code (i.e., which satisfies all the constraints).
If there are no such numbers, output "NONE" (without the quotes).
## Input

* Line 1: A single integer: N
* Lines 2..N+1: Line i+1 contains guess i and its two responses
expressed as three space-separated integers: G_i, C_i, and W_i
## Output

* Line 1: A single integer that is the smallest four-digit number
(same range as the secret integer: 1000..9999) which could be
the secret code. If there are no such numbers, output a single
line containing the word "NONE" (without quotes).
