4..7. LCS Code Implementation

Try these first

1. 1.

   What is the main difference between LCS and exact string matching?

   Hint

   Think about the flexibility of matching.

2. 2.

   Explain what dynamic programming means in the context of LCS.

   Hint

   How does it avoid repeated calculations?

3. 3.

   What does LCS stand for?

   • Longest Common Subword
   • Longest Common Subsequence
   • Longest Character Sequence

   Hint

   Look at context about matching sequences.

4. 4.

   Dynamic programming can significantly improve LCS calculations. True or False?

   • True
   • False

   Hint

   Think about efficiency in complex problems.

5. 5.

   Given two strings, 'abcde' and 'ace', find the length of their LCS and show the sequence.

   Hint

   Consider dynamic programming to calculate the outputs efficiently.

6. 6.

   Calculate the LCS for 'AGGTAB' and 'GXTXAYB' and explain the steps taken.

   Hint

   Fill the table and observe how matches build the length.
