Find the contiguous subarray within an array (containing at least one number) which has the largest sum. For example, given the array[-2,1,-3,4,-1,2,1,-5,4], the contiguous subarray[4,-1,2,1]has the largest sum =6. Analysis 题目隶属于分治类型之下,所以最开始就会从“是否能够拆分...

使用divide and conquer(分治法)查找随机数是一种常见的算法技术,用于在一个包含随机数的数据集中快速定位目标数值。该算法的基本思想是将问题分解为更小的子问题,然后逐步解决子问题,最终得...

Assignment1_Divide_and_Conquer 1 数组中的第k大元素(Leetcode.215) Given an integer array nums and an integer k, please return the k-th largest element in the array. Your algorithm’s runtime complexity must be in the order of \( O(n) \), prove the correctness and analyze the...
Solving by divide-and-conquer Finding the maximum subarray that crosses the midpoint Not a smaller instance of the original problem: has the added restriction that the subarray must cross the midpoint. Again, could use brute force. If size of A[low..mid] is n, would have n/2 choices fo...
分治法(Divide and Conquer)顾名思义,思想核心是将问题拆分为子问题,对子问题求解、最终合并结果,分治法用伪代码表示如下: function f(input x size n) if(n < k) solve x directly and return else divide x into a subproblems of size n/b call f recursively to solve each subproblem Combine the res...
解决(Conquer):递归地求解各子问题。如果子问题规模足够小,则直接求解。 合并(Combine):将所有子问题的解合并为原问题的解。 以leetcode中Maximum Subarray为例: Find the contiguous subarray within an array (containing at least one number) which has the largest sum.For example, given the array[−2,...
