Code in harness

You,Tue Oct 11 2022•dart + flutter

When you do competitive tests, it is good to make sure that your code goes inside a strict route, by putting it in a harness building a small harness is just a couple of extra functions etc; here is an example of a example

one function returns input
one function processes input and returns output
main function uses above two
- takes input
- processes it and gets output
- prints output

using this style is good for testing. happy coding !

//harness
List<double> getInput()
{
  return [1,2,6,341,5,6];
}
 
//find average without dynamic fat arrow functions
double findAverage(List inputValues)
{
  double sum = 0.0;
  
  for(int i = 0; i<inputValues.length;i++)
    {
    sum += inputValues[i];
    }
  
  if(inputValues.isEmpty) return 0;
  
 return (sum/inputValues.length);
}
 
void main() 
{
  List vals = getInput();
  
  double av = findAverage(vals);
  
  print("The average is $av");
  
}

Output:

The average is 60.166666666666664
