- Calculating the number of different substrings of a string.
Introduction to Hashing – Data Structure and Algorithm Tutorials
Hashing refers to the process of generating a fixed-size output from an input of variable size using the mathematical formulas known as hash functions. This technique determines an index or location for the storage of an item in a data structure.
