I have restarted the problem for the third time and I have the same answer. How do I check where I am going wrong. Please help

This is my logical understanding of the problem:

  1. Thief withdrew money from Leggetto Street on the day of robbery
  2. Within 10 min of the incident at 10:15, they exited the parking lot
  3. They called their accomplice for less than a minute. Accomplice buys the ticket(is there any significance to this line- I assumed that only thief is travelling and not the accomplice)
  4. Thief leaves by the first flight on 29 from fifytville

Also does this statement have any connection to the problem - Littering took place at 16:36'. It is displayed while querying description in crime_scene_reports

  • what exactly is your problem? where are you stuck? eveyrthing they tell you is useful and used to cross refernce with other data to figure out the puzzle.

  • how did you get those bits of information? you have to do similar things to get more information by continuing to query the different tables and do different joins to find common people. i dont remember the details well enough to validate your 4 statements of logical understanding... how you got the information is critical to demonstrate the information is correct.

1 Answer 1


If anyone was following this thread, this is for them :) My understanding was right. My answers were also right. But validation was failing because I had modified the answers.txt file with an extra space. Once the extra space was removed, my answers were validated

  • while kinda helpful, this kind of makes your whole question moot. you never explained the exact problem you were having and no one questioned the information you presented initially.

  • My problem was that even when I believed my answers were correct, cs50 validations were failing. Despite me thoroughly rechecking my solutions. All the information I had shared was retrieved by querying the DB they had shared. I agree, my question is moot this point. Hope this helps

  • up voting as it is actually worth noting that apparently its very sensitive to extra whitespace in the acceptor.. youd think theyd trim off leading and trailing spaces.

  • i would upvote the question if you included the original 'answer' but mask your actual answer content like 'xxx xxx` if it was abc def just so you can demonstrate where the whitespace was that had to be deleted.
