sudoku solution review for students

this repo includes 100 solutions (both complete and partial) to the sudoku challenge

the solutions are grouped into 2 folders only to separate those included in the table below (analyzed-solutions) vs the others still to be reviewed (solutions)

all 100 solutions are worth reviewing if only to get a sense of what it feels like to read ~20,000 lines of code :)

it's exhausting.

so, if you want to find a solution that demonstrates something in particular, look at the table below and match the solution id (left column) to the file name in the folder analyzed-solutions

column headers

• Choice of Data Structure

  • Nested the solution uses some kind of nested data structure

  • Array the solution uses an Array as the primary data structure

  • Hash the solution uses a Hash as the primary data structure

  • String the solution uses a String as the primary data structure

• Patterns of Code

  • Single Responsibility the solution effectively demonstrates single responsibility

  • Recursive the solution uses a recursive approach

  • Iterative the solution uses an iterative approach

  • Hardcode Some this column will be removed

  • Megamoth the solution includes on or more impossibly complicated methods

  • Checksum the solution uses a checksum to validate completeness for rows, columsn and boxes

  • Hardcoded the solution manually hardcodes something that could have been calculated

  • Good Naming the solution demonstrates good naming conventions

  • Transpose the solution uses the Array#transpose method

  • Antipattern the solution includes one or more antipatterns

  • Module the solution uses a module for namespacing
