思路: 最短路径的变种,中间限制了结点数。比如当K=1时,表示中间只能进行一次跳转,最长的路径数可以为2。定义:ds[i] 表示从起点src出发,到i,经过最多K次跳转的最短距离。采用松弛法,当经过第k个阶段时,每当有更小的距离时,则更新。

NAND is a non-volatile flash memory which can hold data even when it’s not connected to a power source. The ability to retain data when the power is turned off makes NAND a great option for internal, external and portable devices. USB drives, SSDs and SD cards all utilise flash technology, providing memory for devices such as your mobile phone or digital camera.

Problem Description Lindsay is a shopaholic. Whenever there is a discount of the kind where you can buy three items and only pay for two, she goes completely mad and feels a need to buy all items in the store. You have given up on curing her for this disease, but try to limit its effect on her wallet. You have realized that the stores coming with these offers are quite elective when it comes to which items you get for free; it is always the cheapest ones. As an example, when your friend comes to the counter with seven items, costing 400, 350, 300, 250, 200, 150, and 100 dollars, she will have to pay 1500 dollars. In this case she got a discount of 250 dollars. You realize that if she goes to the counter three times, she might get a bigger discount. E.g. if she goes with the items that costs 400, 300 and 250, she will get a discount of 250 the first round. The next round she brings the item that costs 150 giving no extra discount, but the third round she takes the last items that costs 350, 200 and 100 giving a discount of an additional 100 dollars, adding up to a total discount of 350. Your job is to find the maximum discount Lindsay can get.

对于HashMap内的所有实现来说,首先第一步是定位对键值对所在数组的索引下标位置,这是后续所有操作的基础.
This week, Microsoft and Nvidia announced that theytrained what they claim is one of the largest and most capable AI languagemodels to date: Megatron-Turing Natural Language Generation (MT-NLP). MT-NLPcontains 530 billion parameters — the parts of the model learned fromhistorical data — and achieves leading accuracy in a broad set of tasks,including reading comprehension and natural language inferences.
AWS S3 is an object-based serverless storage service by Amazon web services which is much faster than hard drive file systems and block storage approaches to save data. Serverless means the storage is hosted on the cloud where you don’t have to configure the server with storage space restriction, it gets expanded dynamically with usage.

简单来说是底层最核心的是一个数组,首先它会对key进行一个hash计算,然后根据这个hash值对数组进行取模(取模的结果一定是在0~数组的长度之间),就会定位到数组里的一个下标为index位置上。
