Installing DVWA using DockerInstall the Damn Vulnerable Web Application (via a Docker container) quite easily, as it will take care of all the dependencies required (e.g. mySQL). Open a terminal within your Ubuntu instance. Install DVWA with the following command: sudo docker run —restart always -p 80:80 vulnerables/web-dvwa DVWA should now be installed and running. To access it, open up Firefox and browse to your localhost address. In other words, in the URL toolbar (where you type in URLs)...

Install Docker Compose on UbuntuWhen trying to install Docker Compose with the command: 1sudo apt install docker-compose-plugin you might encounter the following error:1234Reading package lists... DoneBuilding dependency tree... DoneReading state information... DoneE: Unable to locate package docker-compose-pluginThis happens because the default Ubuntu repositories don’t include the latest Docker packages. To fix it, you need to enable the official Docker repository first. Solution Remove old...

Installing Docker in UbuntuDocker (https://www.docker.com/) is an open-source technology that allows for applications to be packaged into ‘containers’ which include any required libraries and other dependencies. This makes it very easy to deploy applications (especially for large enterprises who need to setup their workstations), and you can run more applications on the same amount of hardware (as containers use less resources than virtual machines hosting the applications), among other benef...

DescriptionGiven an array nums of n integers, return an array of all the unique quadruplets [nums[a], nums[b], nums[c], nums[d]] such that: 0 <= a, b, c, d < n a, b, c, and d are distinct. nums[a] + nums[b] + nums[c] + nums[d] == target You may return the answer in any order. 12345678Example 1:Input: nums = [1,0,-1,0,-2,2], target = 0Output: [[-2,-1,1,2],[-2,0,0,2],[-1,0,0,1]]Example 2:Input: nums = [2,2,2,2,2], target = 8Output: [[2,2,2,2]] 12345Constraints:1 <= nums.length <= ...

DescriptionGiven a string containing digits from 2-9 inclusive, return all possible letter combinations that the number could represent. Return the answer in any order. A mapping of digits to letters (just like on the telephone buttons) is given below. Note that 1 does not map to any letters. 1234Example 1:Input: digits = "23"Output: ["ad","ae","af","bd","be","bf","cd","ce","cf"] 1234Example 2:...

DescriptionGiven an integer array nums of length n and an integer target, find three integers in nums such that the sum is closest to target. Return the sum of the three integers. You may assume that each input would have exactly one solution. 12345Example 1:Input: nums = [-1,2,1,-4], target = 1Output: 2Explanation: The sum that is closest to the target is 2. (-1 + 2 + 1 = 2). 12345Example 2:Input: nums = [0,0,0], target = 1Output: 0Explanation: The sum that is closest to the target is 0. (0 ...
