Solution: Interleaving String
Explore a dynamic programming approach to solve the interleaving string problem in JavaScript. This lesson teaches you how to verify if one string can be formed by merging two others while preserving character order, using a space-efficient 1D array for state tracking. You will understand the algorithm's step-by-step logic, time complexity, and space optimization 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:
