I missed that, thanks

Test cases in JS don't work: they all expect empty array [] as solution even if it's not the case, e.g.:

gbwb [ 'bwbg',
'gbwb',
'gbbw',
'bspinqkn',
'ciwsgixm',
'kzhqx',
'updn',
'reuqlsjx',
'gwbb',
'pk',
'bwgb',
'wgbb',
'gwbb',
'or',
'bbwg',
'bjds',
'bgwb',
'gbwb',
'tsjlv',
'gwbb',
'bbgw',
'gvb',
'ovuxojd',
'wgbb',
'wtvth',
'fmcjosc',
'fxnyla',
'gbwb',
'aswglh',
'wgbb',
'kg',
'gwbb',
'qbg',
'vzdwe' ]

Didn't think about it, lol. Thank you!

Need help. My solution passes all sample tests but does not pass random tests at all. Is there a way to check what strings and arrays are generated in test cases so I could go through them? Thanks in advance.

@Calgiles3 In line 4 array with directions is returned or empty array if no direction is found (instead of null). Hope it helps!
