import random
# ------------------------------------------------------------
# Function: generate_number
# Purpose: Create one 3-digit integer with distinct digits,
# drawn from a shared pool of available digits.
# The first digit is never zero, so the result
# is always a true 3-digit integer.
# ------------------------------------------------------------

# Choose the first digit from the pool, excluding '0'

# Choose the remaining digits from the updated pool
remaining = random.sample(available_digits, length - 1)
# Remove chosen remaining digits from the pool
for d in remaining:

# Build the number as a string, then convert to int
digits_str = first_digit + "".join(remaining)

# ------------------------------------------------------------
# Function: generate_three_distinct_digit_numbers
# Purpose: Produce three integers, each with distinct digits,
# and no digit repeated across all three numbers.
# All numbers are guaranteed to be 3 digits long.
