💥 data-structures & algorithms 💥

⭐Data Structures⭐ are the programmatic way of storing data so that data can be used efficiently. ⭐Algorithm⭐ ⭐is a step-by-step procedure, which defines a set of instructions to be executed in a certain order to get the desired output.

Contributing

This repository is open for contributing. You can add new or improve already existing algorithm. I would appreciate if you check out CONTRIBUTING.md file before creating pull request. Thanks for Your time. 😊

Running algorithm

This project is customized to build with Gradle Build Tool. Gradle is an open-source build automation tool flexible enough to build almost any type of software 💚

Build with Gradle

The recommended way to execute any Gradle build is with the help of the Gradle Wrapper. The Wrapper is a script that invokes a declared version of Gradle, downloading it beforehand if necessary. All you need to do is to run commands below:

Wrapper script:

  • ./gradlew -> linux/mac OS
  • gradlew.bat Windows OS

To build whole project use

./gradlew build

build include:

:build
+--- :assemble
|    \--- :jar
|         \--- :classes
|              +--- :compileJava
|              \--- :processResources
\--- :check
     \--- :test
          +--- :classes
          |    +--- :compileJava
          |    \--- :processResources
          \--- :testClasses
               +--- :compileTestJava
               |    \--- :classes
               |         +--- :compileJava
               |         \--- :processResources
               \--- :processTestResources

Run a single algorithm:

./gradlew -PmainClass=<fully-qualified-class-name> runAlgorithm

e.g.

./gradlew -PmainClass=com.marcinseweryn.algorithms.sorting.MergeSort runAlgorithm

Run a single test

./gradlew test --tests com.marcinseweryn.algorithms.sorting.MergeSortTest

e.g.

./gradlew test --tests <fully-qualified-class-name>

Get the test result report in html

./gradlew testReport

Compile and run with JDK

Setup Java

  • Download and install Java

Setup folder structure

  1. Place your class files inside a directory—for example, /home/user/classdir. Note that this directory is the base directory for the package tree. If you add the class com.horstmann.corejava.Employee, then the Employee.class file must be located in the subdirectory /home/user/classdir/com/horstmann/corejava.
  2. Place any JAR files inside a directory—for example, /home/user/archives.
  3. Set the class path. The class path is the collection of all locations that can contain class files.

Compile

javac -classpath/jar MyProg.java

Run

java -classpath classes/jar MyProg

e.g.

java -classpath /home/user/classdir:.:/home/user/archives/archive.jar MyProg

or

java -classpath c:\classdir;.;c:\archives\archive.jar MyProg
