📝 WalkthroughWalkthroughIntroduces a new LeetCode 712 solution that uses dynamic programming to compute the minimum ASCII deletion sum from two strings. The implementation validates inputs, builds a DP table with base cases, and fills it using character-match or deletion-cost minimization. Two JUnit tests validate the algorithm against known outputs.

11-19: ⚡ Quick winAdd boundary tests for empty/equal inputs.
Current tests cover canonical examples, but not base-path behavior (empty strings and already-equal strings), which are important for the DP border conditions.

13-15: ⚡ Quick winFix the DP approach/space complexity wording in Javadoc.
Line 13 describes the method as top-down, but the implementation is bottom-up tabulation (Lines 27–50).
Line 14 also impliesO(min(N, K))space, while current code allocatesrows * cols.Suggested doc-only patch

In `@src/main/java/com/github/mstepan/leetcode/medium/MinimumAsciiDeleteSumForTwoStrings.java` around lines 13 - 15, The Javadoc is incorrect: the implementation in MinimumAsciiDeleteSumForTwoStrings uses a bottom-up tabulation (not top-down) as implemented in the DP loop around lines 27–50, and the space complexity is not O(min(N,K)) because the code allocates a full rows x cols table. Update the Javadoc to say "bottom-up tabulation" (or "iterative DP/tabulation") and set time complexity to O(N*K) and space complexity to O(N*K) (or mention O(min(N,K)) only if you also change the implementation to use a rolling 1D array optimization); keep the method/class name MinimumAsciiDeleteSumForTwoStrings as the reference when updating the comment.

- Around line 11-19: Add boundary tests to
MinimumAsciiDeleteSumForTwoStringsTest to cover empty and already-equal inputs:
add test methods that assert minimumDeleteSum("", "") == 0,
minimumDeleteSum("abc", "") == sum of ascii of "abc" and minimumDeleteSum("",
"abc") == same sum, and minimumDeleteSum("same","same") == 0 so DP border
conditions are validated; locate tests in the class alongside existing
case1/case2 and use the same assertEquals style with the minimumDeleteSum
function name.
