What property of an algorithm refers to the resources it consumes during execution?

The property that refers to the resources consumed during the execution of an algorithm is efficiency. Efficiency typically measures how well an algorithm uses resources such as time (execution speed) and space (memory usage). An efficient algorithm performs its task using the least amount of these resources, making it important for optimizing performance, especially in environments where resources are limited or expensive.

Understanding efficiency helps software developers and computer scientists choose or design algorithms that can handle large inputs or complex tasks without excessive resource consumption, directly impacting the usability and effectiveness of software applications.
