How we get input?
  -> At first we need to create a txt file input.txt where we write our input
  -> Then we need to add some code inside main function
     const t = readline()
     console.log(t)
  -> Finally run command **cat input.txt | node test.js > output.txt** in terminal
Now you can see output inside output.txt file
