Purpose of the technical specification: Implement an algorithm for searching for an equilibrium index in an array of integers. Description. The equilibrium index in an array is defined as the index at which the sum of the elements on the left is equal to the sum of the elements on the right. In other words, it is an index at which the sum of the array elements before that index is equal to the sum of the elements after it. For example, in the array 1, 7, 3, 6, 5, 6, the equilibrium index is 3 because the sum of the elements to the left of index 3 (1 + 7 + 3 is 11) is equal to the sum of the elements to the right of index 3 (5 + 6 is 11) . If the equilibrium index is not found, the function should return -1.
The task was solved using the cli interface and containerized in docker. The task was divided into logical modules in which logic, validation, processing, testing and interface are atomically performed. The input list was also validated and tests were written in the test.
Copy solution from github repo:
git clone git@github.com:yevhenii-nevmyvako/dashdevs-task-solution.gitInstall requirements & setup the project:
python -m venv venv
pip install -e .If you wont install in docker: go to your project folder and run command:
docker build -t <name:tag> . list create from string with integer values.
find_index '5,6,5'Save result to json file with optional flag -f
find_index '5,6,5' -f path/to/save_result.jsonlist create from string with integer values.
docker run <name:tag> find_index '5,6,5'Save result to json file with optional flag -f
docker run find_index '5,6,5' -f path/to/save_result.json
