    Day 14: Parabolic Reflector Dish

    I only managed part 1 today. My enthusiasm for index fiddling is waning rapidly.

      How about not fiddling with indices?

      JQ Notfiddlingwithindexification

      https://github.com/zogwarg/advent-of-code/blob/main/2023/jq/14-a.jq

      #!/usr/bin/env jq -n -R -f

# Dish to grid
[ inputs / "" ]

# Tilt UP
| transpose                       # Transpose, for easier RE use
| map(                            #
  ("#" + add) | [                 # For each column,   replace '^' with '#'
    scan("#[O.]*") | [            # From '#' get empty spaces and 'O' rocks
      "#", scan("O"), scan("\\.") # Let gravity do it's work.
    ]                             #
  ] | add[1:]                     # Add groups back together
 )                                #
| transpose                       # Transpose back

# For each row, count  'O'  rocks
| map(add | [scan("O")] | length)

# Add total load on "N" beam
| [0] + reverse | to_entries
| map( .key * .value ) | add

      Similarly tired with index fiddling, I was pretty happy with my approach, which led to satisfying transpose cancelling in part 2. Not the fastest code out there, but it works. Day 14 was actually my favorite one so far ^^.
