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).


* 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


* 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).
