该简洁代码作者的解释:https://leetcode.com/problems/minimum-cost-tree-from-leaf-values/discuss/339959/One-Pass-O(N)-Time-and-Space Solution DP Find the cost for the interval [i,j]. To build up the interval [i,j], we need to split it into left subtree and sub tree, dp[i, j] =...
Given a set of n jobs with [start time, end time, cost] find a subset so that no 2 jobs overlap and the cost is maximum. Job: (start_time, end_time] --- cost 如果只是求maxCost, 一维就可以做。 但是如果要知道有选了哪些job,则需要存成二维。 1packageleetcode;23importjava.util.Array...
Having the similar thinking with above code, but this solution don't use heap to maintain the ratio, so the time complex is bigger than above. 4|0Time Complexity: O(N^2 \log N)O(N2logN), where NN is the number of workers. __EOF__ 本文作者:Veritas des Liberty 本文链接:https:...
