Learners, PR Template

Self checklist

  • I have titled my PR with Region | Cohort | FirstName LastName | Sprint | Assignment Title
  • My changes meet the requirements of the task
  • I have tested my changes
  • My changes follow the style guide

Changelist

  • Implemented push_head, pop_tail, and remove with O(1) complexity
  • Used node handles from push_head for direct removal in remove
  • Handles edge cases in pop_tail and remove for empty/single-element lists

Questions

  1. Are node objects from push_head suitable as handles for remove?
  2. Should we add utility methods like is_empty() alongside core functions?

Why not also clean up reference in pop_tail()?
