Which of the following explains different types of efficiency?
a. Time complexity refers to the amount of memory used. Space complexity refers to the amount of time needed.
b. Space complexity refers to the amount of memory used. Time complexity refers to the amount of time needed.
c. Code length refers to the number of characters in the code. Code complexity refers to the effort needed to understand the code.
d. Code complexity refers to the number of characters in the code. Code length refers to the effort needed to understand the code.
b. Space complexity refers to the amount of memory used. Time complexity refers to the amount of time needed.
The correct answer is:
b. Space complexity refers to the amount of memory used. Time complexity refers to the amount of time needed.
In computer science, efficiency is often measured using two main factors: time complexity and space complexity. Time complexity refers to the amount of time a program or algorithm takes to run, while space complexity refers to the amount of memory or storage space required.
Option b correctly explains that space complexity refers to the amount of memory used, and time complexity refers to the amount of time needed.
