Data Structures & Algorithms
DSA is like learning to organize your toys AND the best way to find them. Data Structures are the boxes and shelves (HOW you store things). Algorithms are the steps you take to find what you need (HOW you search).
Think of it like this...
Imagine your room. You could throw all toys in a pile (messy!). Or use labeled boxes by type—LEGO, cars, dolls. When you want a specific LEGO set, you go straight to the LEGO box. That's a data structure with an algorithm!

Google Maps — Graph algorithms in navigation
Google Maps uses Dijkstra's algorithm (and optimized variants like A*) to find shortest paths between locations. The road network is a weighted graph with millions of nodes.
