// Solution 1: An interesting problem. As the elements are all integers, if not encountering 0, the absolute value of the product will continue to increase. Thus the product is either min or max. By keeping watch over both ends, we have the maximum product of subarrays. This holds only...

53. 最大子数组和 - 给你一个整数数组 nums ,请你找出一个具有最大和的连续子数组(子数组最少包含一个元素),返回其最大和。 子数组 是数组中的一个连续部分。 示例 1: 输入:nums = [-2,1,-3,4,-1,2,1,-5,4] 输出:6 解释:连续子数组 [4,-1,2,1] 的和最大,为
Can you solve this real interview question? Pow(x, n) - Implement pow(x, n) [http://www.cplusplus.com/reference/valarray/pow/], which calculates x raised to the power n (i.e., xn). Example 1: Input: x = 2.00000, n = 10 Output: 1024.00000 Example
请你设计并实现一个满足LRU (最近最少使用) 缓存约束的数据结构。 实现LRUCache类: LRUCache(int capacity)以正整数作为容量capacity初始化 LRU 缓存 int get(int key)如果关键字key存在于缓存中,则返回关键字的值,否则返回-1。 void put(int key, int value)如果关键字key已经存在,则变更其数据值value;如果...
