This a task that asks u to compute the maximum product from a continue subarray. However, you need to watch out the values' type contains positive, negative, zero. I solved it using dynamic process in which there are two arrays to achieve the goal. m…

Maximum Product Subarray Given an integer array nums, find the contiguous subarray within an array (containing at least one number) which has the largest product. Example 1: Input: [2,3,-2,4] Output: 6 Explanation: [2,3] has the largest product 6. Ex…

Find the contiguous subarray within an array (containing at least one number) which has the largest product. For example, given the array [2,3,-2,4],the contiguous subarray [2,3] has the largest product = 6. [题目分析] 给定一个整数数组,找出数组中的一个子序列,使得序列中所有元素的乘积最大…

题目: Find the contiguous subarray within an array (containing at least one number) which has the largest product. For example, given the array [2,3,-2,4], the contiguous subarray [2,3] has the largest product = 6. 提示: 这道题可以使用动态规划求解,但是由于是乘法运算,所以情况更加复杂.…

53. Maximum Subarray 之前的值小于0就不加了.dp[i]表示以i结尾当前的最大和,所以需要用一个变量保存最大值. 动态规划的方法: class Solution { public: int maxSubArray(vector<int>& nums) { vector<int> dp(nums.size()); int res = INT_MIN; ;i < nums.size();i++){ dp[i] = nums[i]; &&…

Question 152. Maximum Product Subarray Solution 题目大意:求数列中连续子序列的最大连乘积 思路:动态规划实现,现在动态规划理解的还不透,照着公式往上套的,这个问题要注意正负,需要维护两个结果 Java实现: public int maxProduct(int[] nums) { if (nums.length == 1) return nums[0]; // 定义问题:状态及对状态的定义 // 设max[i]表示数列中第i项结尾的连续子序列的最大连…

题目链接:Maximum Product Subarray solutions同步在github 题目很简单,给一个数组,求一个连续的子数组,使得数组元素之积最大.这是求连续最大子序列和的加强版,我们可以先看看求连续最大子序列和的题目maximum-subarray,这题不难,我们举个例子. 假设数组[1, 2, -4, 5, -1, 10],前两个相加后得到3,更新最大值(为3),然后再加上-4后,和变成-1了,这时我们发现如果-1去加上5,不如舍弃前面相加的sum,5单独重新开始继续往后相加…

Given an integer array nums, find the contiguous subarray within an array (containing at least one number) which has the largest product. Example 1: Input: [2,3,-2,4] Output: 6 Explanation: [2,3] has the largest product 6. Example 2: Input: [-2,0,-1]…

Find the contiguous subarray within an array (containing at least one number) which has the largest product. For example, given the array [2,3,-2,4],the contiguous subarray [2,3] has the largest product = 6. 题目标签:Array, Dynamic Programming 题目给了我们一个nu…
