Basic Algorithm Efficiency Awareness
Algorithm efficiency awareness means noticing that different ways of solving the exact same problem can take very different amounts of time or memory to run, and that this difference often becomes much more noticeable as the amount of data involved grows larger. For example, searching through an unsorted list of a million items one entry at a time can, in the worst case, take far longer than searching a list of only ten items, even though both searches use the exact same basic method.
