Maximum Subarray 最新更新请见:https://yanjia.me/zh/2019/02/... 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 ...
Explanation: [2,3] has the largest product 6. Example 2: Input: [-2,0,-1] Output: 0 Explanation: The result cannot be 2, because [-2,-1] is not a subarray. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. class Solution { ...
the contiguous subarray [2,3] has the largest product = 6. 从一个整数数组中找到一个子数组,该子数组中的所有元素的乘积最大。 比如数组[2,-3,-2,4]的最大乘积子数组为[2,3] 思路与代码 这题目考察了动态编程的思想。从一个更高的视角看这个问题,我们可以推理一下,假如我们知道了以第i位为结尾的...
