Data Structures and Algorithms

77 Posts
Methods to store, organize & process data efficiently for speed and memory optimization. DSA (Data Structures & Algorithms) means organizing data efficiently (arrays, trees, graphs, hash maps) and using step-by-step logic (sorting, searching, traversal) to solve problems quickly and with minimal memory — the foundation for building software that performs well at large scale.
