Valid Palindrome 126*. So, after converting our input triangle elements into a regular matrix we should apply the dynamic programming concept to find the maximum path sum. ms is the minimum paths through the row below (and on the initial pass will just be the bottom row) and for each n in our row ns, if we're at the rightmost element, we just copy the value from the corresponding row below, otherwise we take the minimum of the element right below and the one to its right. 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. Output: 42Explanation: Max path sum is represented using green color nodes in the above binary tree. Example 3: Input: root = [], targetSum = 0 Output: false Explanation: Since the tree is empty, there are no root-to-leaf paths. Given a triangle, find the minimum path sum from top to bottom.
