'Where you place it' determines the speed of a program. Computers are fast at calculation, but if you choose the wrong place to store data, it will be slow no matter how fast the CPU is. Conversely, ...

This course provides a comprehensive introduction to data structures and algorithms used in computer science. Throughout the course, students will learn how to write efficient code, analyze algorithms ...

This avoids a full BFS per query; we only walk up the tree, which in the worst case is O(tree height). For a balanced tree the height is O(log N), but for a line it degrades to O(N). Still, it is much ...
