所以要务必反复练习做过的作业题目。这个和和大厂面试的Leetcode题目通关是类似的,需要尽可能地多刷题,包括leetcode的相对应的典型DC和DP题目,和印度人搞的GeeksforGeeks上面的Graph算法理论题目。也可以找其它学校的类似考试题目刷题练手。 第三,课程内容不能光看,要尽量动手编程实现。有些算法可以通过编程来跟踪循...
原文链接http://www.geeksforgeeks.org/pseudo-polynomial-in-algorithms/ 什么是伪多项式? 当一个算法的最坏时间复杂度是依据输入的数量级的时候,我们就称算法的时间复杂偶是伪多项式时间(给一个wiki上的解释可能更好理解 若一个数值算法的时间复杂度可以表示为输入数值规模N的多项式,但其运行时间与输入数值规模N的...
https://www.geeksforgeeks.org/dijkstras-shortest-path-algorithm-greedy-algo-7/ 最短路算法。 Given a graph and a source vertex in the graph, find the shortest paths from the source to all vertices in the given graph. Dijkstra’s algorithm is very similar toPrim’s algorithm for minimum spa...
Quicksort is similar to MergeSort in that the sort is accomplished by dividing the array into two partitions and then sorting each partition recursively. In Quicksort, the array is partitioned by placing all items smaller than some pivot item before that item and all items larger than the piv...

打算把https://www.geeksforgeeks.org/top-algorithms-and-data-structures-for-competitive-programming/ 复习一遍,今天是第一章,主要是讲图论算法。 https://www.geeksforgeeks.org/breadth-first-traversal-for-a-graph/ 例题https://practice.geeksforgeeks.org/problems/x-total-shapes/0 ...
In this example the largest element (7) is bubbled to the top. The process would then repeat until no further changes could be made. https://www.geeksforgeeks.org/python-program-for-bubble-sort/ An example in python Last but not least!
KMP on geeksforgeeks, with a well-commented C code. I am sorry that I am still inable to give a personal explanation of the algorithm. I only read it from the two links above and mimic the code in the second link. You may use this code to solve the problemImplement strStr()on Leet...
