Number baseball 5

This is a number baseball game.

The secret is a four-digit string. Each digit is from 0 to 9, and no digit is used more than once. The first digit may be 0.

Compare a guess with the secret as follows.

• A digit that appears in the secret at a different position is a ball.
• A digit that matches both value and position is a strike.

The original statement drew a new secret every 5 minutes (minute 0, 5, ..., 50, 55) and scored $10$ times the number of strikes plus the number of balls. Here the secret is fixed as $1234$. Print exactly $1234$.

This problem has no input.

Print $1234$ on the first line. The rule that a number may start with 0 describes the format. The required answer is $1234$.

If the secret were $5134$, the guesses below would score as follows. In this problem the secret is $1234$, so the list only explains the rules.

• $2479$ gives 0 strikes and 1 ball (1 point)
• $3167$ gives 1 strike and 1 ball (11 points)
• $4165$ gives 1 strike and 2 balls (12 points)
• $5143$ gives 2 strikes and 2 balls (22 points)
• $5134$ gives 4 strikes and 0 balls (40 points)
