Question
1
Explanation
What is an algorithm?
An algorithm is a sequence of computational steps that converts input into the output. It is a finite set of rules or a procedure to solve a problem.
Question
2
Explanation
What is time complexity?
Time complexity is a procedure to measure the efficiency of an algorithm.
It is the time needed by an algorithm expressed as a function of the size of a problem is.
The time complexity of a program is the amount of computer time it needs to run to completion.
Question
3
Explanation
What is worst-case efficiency?
The worst-case efficiency of an algorithm is its efficiency for the worst-case input of size n, which is an input or inputs of size n for which the algorithm runs the longest among all possible inputs of that size.
Question
4
Explanation
What is worst-case efficiency?
