Your solution for Pascal's Triangle is correct and efficient. Well done! The code is clean and well-commented. Here are a few suggestions for improvement:

1. You can avoid the special case for i=0 by initializing the result with the first row and then looping from i=1 to numRows-1. This might make the code slightly more concise.

For example:

List<List<Integer>> result = new ArrayList<>();
if (numRows == 0) return result;
result.add(Arrays.asList(1));
for (int i = 1; i < numRows; i++) {
    List<Integer> prev = result.get(i-1);
    List<Integer> current = new ArrayList<>();
    current.add(1);
    for (int j = 1; j < i; j++) {
        current.add(prev.get(j-1) + prev.get(j));
    }
    current.add(1);
    result.add(current);
}
return result;

2. Although your current solution is correct, note that the inner loop condition j <= i - 1 is equivalent to j < i. Using j < i might be more intuitive.

3. Ensure that you only submit the solution for the problem you are solving. The inclusion of the K-diff Pairs solution in the same file is not appropriate for this context.

Overall, your solution is excellent. Keep up the good work!
