Hash table

A hash table is a data structure where keys are mapped to index values. This is implemented in programming using arrays or lists. Hash tables are generally used in areas where faster searching is required such, as lookup tables.

This A Level Computer Science module introduces hash tables to your students, explaining:

  • Hashing
  • Implementing hash tables
  • Hashing algorithms
  • Dictionary
