Amitava, can you give a clearer idea of what your function inputs and outputs should look like?

Oleg Komarov on 28 Jan 2012

If you leave one test the solution is simply 9. As is this submission is very poor.

Franck Dernoncourt on 28 Jan 2012

Needs generalization and a larger test suite.

This is a pretty good idea for a problem but it's *very* poorly stated.

Ned Gulley on 2 Feb 2012

I cleaned up the problem statement and added a few more tests.

Mahesh on 2 Apr 2013

good idea...

Daniel Pereira on 15 Apr 2013

Very good problem. I had to solve the same one to determine whether a signal was oscillating or stable.

This user (mohamed elbesealy) appears to have gamed the system, with fraudulent "likes" of this unremarkable solution submitted by 'sock-puppet' accounts. —DIV

Your function is named abc--the test suite wants it to be named your_fcn_name.

What's the wrong with this solution? It works perfectly on the Matlab R2015b.

sumabs is a function from Neural Network Toolbox which is not supported in Cody.

What is the problem with this solution? It works on matlab

Andrew Small on 17 Mar 2015

The test suite expects the function's name to be 'your_fcn_name', instead of distanceWalked. (Which would have been a much more sensible name.)
