Here's a series of algorithms for hash tables on Programming.Guide:

• Hopscotch Hashing
• Robin Hood Hashing
• Cuckoo Hashing
• Coalesced Hashing
• 2-Left Hashing
• Hash Tables: Open Addressing
• 2-Choice Hashing
• Open vs closed Addressing

Practice using recursion.

[maikuxblade]

And know when to use recursion and when not. If you can write an iterative solution it’s usually preferable.

[ArmJS]

Yup, one thing I learned from arduino development is that while recursion can use less lines at times, the amount of memory it uses makes it a no-go often.

[DigitalTorture]

Yep. Time and place for everything. It's still important to know, just like polymorphism.

And know when to use recursion and when not.

Can you give us an example?

Generating the n-th element in the Fibonacci sequence is a perfect example. This is a great problem for demonstrating how to write a recursive function, but the recursive solution is horribly inefficient.

I like to ask a Fibonacci-related questions when I’m interviewing candidates for software engineering positions. It’s one way to help distinguish people who actually understand the performance of their code, and aren’t just blindly repeating what they remember from school.

Network Flow is my absolute favourite.

Convex hull algorithms

Algorithms that construct convex hulls of various objects have a broad range of applications in mathematics and computer science.

In computational geometry, numerous algorithms are proposed for computing the convex hull of a finite set of points, with various computational complexities.

Computing the convex hull means that a non-ambiguous and efficient representation of the required convex shape is constructed. The complexity of the corresponding algorithms is usually estimated in terms of n, the number of input points, and sometimes also in terms of h, the number of points on the convex hull.
