K8S单节点部署


最近尝试学了一下K8S,感觉还行吧!只是对于我自己的项目来说还没必要,弄个docker就不错了,集群对于小项目来说部署有点夸张。个人看了这几天发现官方的交互式教程还是挺爽的,简单了解还是可行的。我这就弄个从头到尾的单节点部署让大家了解一下,可能稍微有点乱。 官方教程:https://kubernetes.io/zh/docs/home/ 安装 docker 安装 安装 curl -fsSL https://get.docker.com | bash -s d......

Multiply Strings


Given two non-negative integers num1 and num2 represented as strings, return the product of num1 and num2, also represented as a string. Note: You must not use any built-in BigInteger library or convert the inputs to integer directly.【The sadest things which I can found the fastest soultion in leetcode break this rule.】 https://leetcode.com/problems/multiply-strings/ Solut......

配置 Pod 以使用 PersistentVolume 作为存储


最近了解这个k8s在PVC存储这儿卡了两天,今天终于算是大概搞明白是个怎么回事了。 以下是该过程的总结: 创建由物理存储支持的 PersistentVolume。你不会将卷与任何 Pod 关联。 创建一个 PersistentVolumeClaim, 它将自动绑定到合适的 PersistentVolume。 创建一个使用 PersistentVolumeClaim 作为存储的 deployment https://kubernetes.io/zh/docs/tasks/configure-pod-container/con......

Interval List Intersections


You are given two lists of closed intervals, firstList and secondList, where firstList[i] = [starti, endi] and secondList[j] = [startj, endj]. Each list of intervals is pairwise disjoint and in sorted order. Return the intersection of these two interval lists. A closed interval [a, b] (with a <= b) denotes the set of real numbers x with a <= x <= b. The inter......

Merge Intervals


Given an array of intervals where intervals[i] = [starti, endi], merge all overlapping intervals, and return an array of the non-overlapping intervals that cover all the intervals in the input. https://leetcode.com/problems/merge-intervals/ Solution submit code class Solution: def merge(self, intervals: List[List[int]]) -> List[List[int]]: if len(intervals) =......

Remove Covered Intervals


Given an array intervals where intervals[i] = [li, ri] represent the interval [li, ri), remove all intervals that are covered by another interval in the list. The interval [a, b) is covered by the interval [c, d) if and only if c <= a and b <= d. Return the number of remaining intervals. https://leetcode.com/problems/remove-covered-intervals/ Solution submit c......

Stone Game


Description Alice and Bob play a game with piles of stones. There are an even number of piles arranged in a row, and each pile has a positive integer number of stones piles[i]. The objective of the game is to end with the most stones. The total number of stones across all the piles is odd, so there are no ties. Alice and Bob take turns, with Alice starting first. Each turn, a player t......
