Solution: Interleaving String
Explore a dynamic programming approach to determine if one string can be formed by interleaving two others while preserving character order. This lesson guides you through optimizing the solution using a one-dimensional DP array, improving space efficiency without losing clarity. Learn to implement and analyze the solution's time and space complexities, enhancing your grasp of dynamic programming techniques.
We'll cover the following...
Statement
You’re given three strings: s1, s2, and s3. Your task is to determine whether s3 can be formed by interleaving s1 and s2.
Interleaving means you take both strings and break them into smaller pieces (substrings), then merge those pieces while preserving the left-to-right order of characters within each original string.
The final mixed string might look like any of the following:
