Strengths:

• The logic for both problems is correct and well-implemented.
• The use of a frequency map in KDiffPairsInAnArray is efficient and avoids duplicate pairs.
• The comments are helpful and explain the thought process clearly.

Areas for Improvement:

• In PascalsTriangle, consider initializing the currentRow with the correct size upfront (e.g., new ArrayList<>(rowNum + 1)) to avoid dynamic resizing.
• Variable names could be more descriptive (e.g., numOfPairs could be count or result).
• For PascalsTriangle, the initial check for numRows == 1 could be avoided by directly starting the loop from rowNum = 1 and handling the first row inside the loop.
