Foxbox Digital N-Grams Code Challenge

This is a small programming problem to test your technical ability and coding style.

Instructions

Write a simple script to generate a set of n-grams from a string of text. N-grams are a contiguous sequence of n words from a string of text, and have many applications from full-text search indexes to machine learning.

You'll generate a set of every permutation of contiguous n-grams from a string of text, from 1-gram to n-grams where n is the number of words in the string

Note for community:

A. IdentityServer3 docs, samples and source code use OIDC & OAuth2 terms interchangeably to refer to same thing in many areas. I think that's make sense because OIDC introduced as complement & extension for OAuth2.

B. IdentityServer3, STS, OP, OIDC server, OAuth2 server, CSP, IDP and others: means same thing (software that provide/issue tokens to clients) as explained in [Terminology] (http://identityserver.github.io/Documentation/docs/overview/terminology.html).

C. Grants and flows mean same thing, grant was the common term in OAuth2 specs and flow is the common term in OIDC specs.

D. This document will not focus on custom flow/grant.

E. [Important] Choosing wrong flow leads to security threat.
