Fixed-Length Paths 2 Approach 1: you can use centroid decomposition here as well but this time sum of all nodes in depth range [k1−d,k2−d][k1−d,k2−d] must be added to ansans. This is because all of these

So dp[i][x] = dp[i-1][x] + dp[i-1][x-i]. The complexity is O(n3)O(n3). Code Increasing Subsequence (1145) This is a classical problem called Longest Increasing Subsequence or LIS for short. dp[x] = minimum ending value of an increasing subsequence of length x+1, using the...
