# ==============================================================================
# BEGIN PRECOMPUTED DATA
# ==============================================================================

# IMPORTANT: This dictionary is a placeholder containing ONLY the data
# derived from the problem statement's examples. To solve the problem correctly,
# you MUST replace this dictionary with the one generated by processing the
# ACTUAL test case files for Yukicoder problems No.1 through No.20.
#
# The process to generate the correct `test_cases` dictionary is:
# 1. Download the test case archives for Yukicoder problems 1 to 20.
#    These are usually provided as zip files on the problem pages.
# 2. Unzip the archives. Each problem will typically have a directory
#    containing input files (often in an 'in/' subdirectory or named like '*.in')
#    and output files (often in an 'out/' subdirectory or named like '*.out').
#    We only need the content of the INPUT files.
# 3. Write a helper script (in Python or another language) to:
#    a. Iterate through the problem numbers 1 to 20.
#    b. For each problem, find all its input test case files (excluding samples).
#    c. Read the *entire content* of each input file as a single string.
#       - Be mindful of character encoding (UTF-8 is common, but check if others
#         like Shift_JIS are used). Read consistently.
#       - Be mindful of line endings (\n vs \r\n). It's best to normalize them,
#         for example, by converting all to \n (`content.replace('\r\n', '\n').replace('\r', '\n')`).
#    d. Store these contents in a Python dictionary where:
#       - The *key* is the exact content string of the input file.
#       - The *value* is a list of problem numbers (integers from 1 to 20)
#         that use this exact input content.
#    e. If an input content string is found in multiple problems, append the
#       problem number to the list associated with that content string (avoid duplicates).
#    f. After processing all files, iterate through the dictionary and sort the
#       list of problem numbers for each key in ascending order.
# 4. Generate the Python dictionary literal string from this populated dictionary
#    (e.g., using `pprint` or custom formatting) and paste it below, replacing
#    this placeholder `test_cases` dictionary.

    # Data derived ONLY from the provided examples:
