Here both loops start at the bottom right corner and the colOffset prevents the second loop from unnecessarily going over the zeros. int size = lists.get(i).size(); for(int j = 0; j < size; j++){ My logic is to find the minimum number in each array and add that to the sum. Method 2: DP Top-DownSince there are overlapping subproblems, we can avoid the repeated work done in method 1 by storing the min-cost path calculated so far using top-down approach, Method 3: DP(Bottom UP)Since there are overlapping subproblems, we can avoid the repeated work done in method 1 by storing the min-cost path calculated so far using the bottom-up approach thus reducing stack space, Method 4: Space Optimization (Without Changning input matrix)We do not need a 2d matrix we only need a 1d array that stores the minimum of the immediate next column and thus we can reduce space. for (int j = 0; j < triangle.get(i + 1).size() - 1; j++) { for (int i = a.size() - 2; i >= 0; i--) { Why lexigraphic sorting implemented in apex in a different way than in other languages? } For example, if you are on number 12 in the fourth row, you can only traverse to 9 or 2 in the fourth (top to bottom) row, as these are the only two numbers .
