Description

This repo will contain the solutions for https://www.algoexpert.io/ Each solution will reside in its own file with propper summary + tests

formatting

using vscode

1. on vs-code go to Code > Preferences > Settings
2. look for format on save
3. check Editor: Format On Save option
4. check Editor: Format On Save Mode option is set to file

using clang-format

• pre-commit: https://pre-commit.com/ MacOSX: brew install pre-commit Linux: pip install pre-commit

• clang-format MacOSX: brew install clang-format Linux: sudo apt install clang-format

2. install pre-commit hooks in the repo: on ./githooks folder run: pre-commit install this will prevent to commit unformatted code

3. execute format script: from root folder run: ./script/format.sh this will format all ur *.cpp and *.h files

bazel

1. install Bazel build system: https://bazel.build/install MacOSX: brew install bazel Linux: sudo apt update && sudo apt install bazel

2. commands from root directory:

    bazel build //lib:utils
    bazel run //exercises/1-two-number-sum:main
    bazel run //exercises/2-validate-subsequence:main
    bazel run //exercises/3-sorted-squared-array:main
    bazel run //exercises/4-tournament-winner:main
    bazel run //exercises/5-non-constructible-change:main
    bazel run //exercises/6-minimum-waiting-time:main
    bazel run //exercises/7-class-photos:main

    bazel test --test_output=errors //tests:tests

OLD

prerequicites

1. install g++ and clang for ur OS check installation versions:

g++ --version
clang --version

2. install vscode https://code.visualstudio.com/download
3. install cpp extension https://code.visualstudio.com/docs/languages/cpp
4. build the program open the file in vscode and from it execute: Terminal > Run Build Task
5. execute the program go to ./bin directory and run executable file

./exercises/<exercise>/bin/main

ie:

./exercises/1-two-number-sum/bin/main

buid exercise

from root folder, execute:

g++ -std=c++11 -fdiagnostics-color=always -g ./<exercise>/main.cpp -o ./<exercise>/bin/main

where main is the file name of a solution to the we want to build and the name of the executable being created under the exercise /bin/ folder. ie:

g++ -std=c++11 -fdiagnostics-color=always -g ./exercises/1-two-number-sum/main.cpp -o ./exercises/1-two-number-sum/bin/main

operation scripts

from root/scripts folder you can

• build.sh $excercise
  • script to build an excercise
  • this will create a /bin directory inside the exercise folder
• run.sh $excercise
  • script to run an excercise
  • this will execute the ./bin/main.cpp file generated from build process
• clean.sh
  • script to clean all exercises
  • this will remove all /bin directories in exercises, only keeping .gitkeep files
