Create a clearer hierarchy for topics

[lnishan]

(This is a continued discussion from here)

Topics

• Binary and Ternary Search
• Dynamic Programming
• Flow
• Game Theory
• Graphs
• Greedy
• Maths
• Matrix Exponentiation
• Miscellaneous
• Prefix and Suffix Trees
• Segment Trees
• Trees

In regard to the current Table of Contents (as quoted above), I suggest a possible restructure and create a clearer hierarchy for topics.

I would propose something like this (here I'll leave the decision of alphabetical order to you -- which I have explained my concerns for it in earlier discussions):

Topics

• Binary and Ternary Search
• Data Structures
  • Prefix and Suffix Trees
  • Segment Trees
  • Trees
• Dynamic Programming
• Game Theory
• Graphs
  • Flow
  • Some other content (eg. Connected Components, Bipartite Graphs and Matchings)
• Greedy
• Maths
  • Matrix Exponentiation
  • Some other content 2 (eg. Sieve of Eratosthenes, Prime Factorization)
• Miscellaneous

(still in alphabetical order)
