给你一个整数数组 nums ,请你找出数组中乘积最大的非空连续子数组(该子数组中至少包含一个数字),并返回该子数组所对应的乘积。
nums
测试用例的答案是一个 32-位 整数。
子数组 是数组的连续子序列。
示例 1:
输入: nums = [2,3,-2,4] 输出: 6 解释: 子数组 [2,3] 有最大乘积 6。
示例 2:
输入: nums = [-2,0,-1] 输出: 0 解释: 结果不能为 2, 因为 [-2,-1] 不是子数组。
提示:
-10 <= nums[i] <= 10
Language: JavaScript
/** * @param {number[]} nums * @return {number} */ var maxProduct = function (nums) { let min = 1, max = 1, res = -Infinity for (let num of nums) { if (num < 0) [min, max] = [max, min] max = Math.max(num * max, num) min = Math.min(num * min, num) res = Math.max(res, max) } return res }
