What are some common algorithmic techniques used in programming?

Common algorithmic techniques include sorting, searching, dynamic programming, and greedy algorithms.

Can you explain dynamic programming with an example?

Sure! Dynamic programming is used to solve problems by breaking them down into simpler subproblems. For example, the Fibonacci sequence can be calculated efficiently using dynamic programming by storing previously computed values.

What about greedy algorithms? How do they differ from dynamic programming?

Greedy algorithms make the locally optimal choice at each stage with the hope of finding a global optimum. Unlike dynamic programming, they do not consider the overall problem structure.

Can you give me an example of a problem that can be solved using a greedy algorithm?

A classic example is the coin change problem, where you want to make change for a certain amount using the fewest coins possible.
