6.1.4. Ignoring Constants in Analysis

Try these first

1. 1.

   What is meant by 'input size' in algorithm analysis?

   Hint

   Think about how many elements you need to sort or check.

2. 2.

   Why do we consider worst-case scenarios?

   Hint

   Consider what happens in the least favorable conditions.

3. 3.

   What does worst-case analysis help determine?

   • Average time for an algorithm
   • Maximum time for an algorithm
   • Minimum time for an algorithm

   Hint

   Consider which scenario would take the longest to resolve.

4. 4.

   True or False: Average-case analysis is always easier to compute than worst-case analysis.

   • True
   • False

   Hint

   Think about the number of scenarios to consider.

5. 5.

   Analyze a sorting algorithm that has a worst-case performance of O(n^2). Determine if you would recommend it for large datasets and justify your decision.

   Hint

   Consider the implications of n being very large.

6. 6.

   Explain how ignoring constants can affect the perceived efficiency of an algorithm when comparing two similar algorithms.

   Hint

   Think about how constants might distort comparisons.
