I've made some changes since this was introduced:

• We now filter out traps that were never triggered, and we now sort based on the count of traps.
• As mentioned above, we now print based on "Valid Inputs" instead of "Total Inputs". Its not ideal but hopefully a temporary solution.

Here's the example output:
