What’s the best approach when data structures are being built from scratch? or How do you optimize pe

Honestly, when data structures are being built from scratch, I always start with the simplest thing that works—like a dynamic array—and then profile later.

If resizing is killing performance, maybe pre-allocate a rough estimate? Or use a language with better built-in growth strategies (Python lists are surprisingly good at this).

For tools, check out VisuAlgo (visualgo.net) to see how different structures handle growth. Saved me a ton of headaches!
