Space complexity examines the amount of memory a computer program needs to run. In programming, space and time complexities are the two sides of the performance equation. For a given task, you try to design an algorithm that minimizes the amount of resources it consumes and produces the correct results. Space complexity deals with memory and time complexity deals with time.
Understanding Space Complexity
Space complexity refers to how much memory a computer program needs to run. It measures the amount of memory that a program occupies while it is running. Space complexity is typically measured in terms of the number of bytes of memory that the program uses.
