computational complexityWe consider the problem of sorting a multiset of size n containing m distinct elements, where the i th distinct element appears n i times. Under the assumption that our model of computation allows only the operations of comparing elements and moving elements in the memory,...

另一种方法是用BFS类似Topological Sorting中的Kahn方法。先计算每个节点的degree,然后把低degree的节点leaf放入queue中进行处理,一层一层把低degree节点逐渐剥离,最后剩下的1 - 2个节点就是解。 Java: 超时的longest path找中点 Time Complexity - O(n2), Space Complexity - O(n) <- TLE publicclassSolution ...

Given an array of integers (duplicates are possible), find the minimum number of swaps to sort the array. For [3,9,2,4,2] it should be 2 : [3, 9, 2, 4, 2] -> [2, 9, 3, 4, 2] -> [2, 2, 3, 4, 9] If the elements are distinct then there's a time complexity O...
Unit 3 Session 1 (Click for link to problem statements) U-nderstand Understand what the interviewer is asking for by using test cases and questions about the problem. What if word1 and/or word2 are not in the list of words? In those cases, we will return -1. P-lan Plan the ...
// If using a pre-sorted list: (no need to use PQ) // Sorting takes O(ElogE) // O(E + E + Elog*V + Vlog*V + V) // = O(Elog*V)}Runtime Analysis See the pseudocode for details.Note: log∗Vlog∗V is the iterative logarithm which is less than 5.Assume all PQ ope...
