Answer

To select the swimmers for the final:

  1. Start: Initiate the process with the heat results.

  2. Input Heat File: Read from the Heat_File data structure, focusing on the swimmer data, which includes swimmer number (SN), heat winner status (W), and heat time (T).

  3. Decision Point: Check if the heat winner (W) is 'Y'. If yes, classify as qualified for the final.

  4. Alternate Path: If W is 'N', compare the swimmer's heat time T with the fastest three times across heats.

  5. Decision Point: Count total qualifying swimmers. If less than 9 total qualifiers (heat winners + fastest losers), continue adding faster times until the quota is filled.

  6. Output Selection: Once the final group of swimmers is established, indicate these swimmers as qualified for the final.

  7. End: Conclude the process.

Answer

To check entries for an event:

  1. Start: Begin the entry checking process.

  2. Input Entries: Determine the number of entries.

  3. Decision Point (entries < 18): Check if the number of entries is less than 18.

    • If 'Yes', proceed to the next step.
    • If 'No', signal that entries are full and proceed to End.

  4. Membership Check: Verify if the member's status allows participation in the event. Decision point:

    • If 'valid membership', confirm entry.
    • If 'not valid membership', output denial message.

  5. End: Conclude the entry checking process, summarizing accepted entries.
