Question 1.
Define Longest Common Subsequence.
Show hintHide hint
Think about how sequences can match but still differ.
Question 2.
What does dynamic programming help achieve in LCS computation?
Show hintHide hint
Remember the method of breaking down problems.
3Question 3.
What is the primary function of the Longest Common Subsequence (LCS)?
- Finding the shortest subsequence
- Identifying the longest ordered matching subsequence
- Sorting characters in order
Show hintHide hint
Consider the goal of matching instead of sorting.
4Question 4.
True or False: In LCS, the order of characters does not matter.
- True
- False
Show hintHide hint
Think about how subsequences are defined.
Question 5.
You have two words, 'ABCDGH' and 'AEDFHR'. Calculate the LCS and explain your reasoning.
Show hintHide hint
Look for the longest matching order.
Question 6.
Describe how you would implement LCS using dynamic programming and address any challenges you might face.
Show hintHide hint
Focus on how to manage the boundaries and tracking of indices.
