Find the pairs in an array whose sum of a number N

create a function that finds pairs of integers from a list that sum to a given value. The function will take as input the list of numbers as well as the target sum.

create a command line tool that takes as command line arguments a comma separated list of integers, and the target integer.

You can assume that all input values are integers. You can assume that there aren't any repeat values in the list.

npm run test

and run with custom inputs -a -> numbers separated by comma, example: 1,2,3,4 -n -> integer number, example: 4

npx algo-find-pair -a 1,9,5,0,20,-4,12,16,7 -n 12  

Before any execution we need install dependencies

npm install

node . -a 1,9,5,0,20,-4,12,16,7 -n 12
