I am getting wrong answer when I m changing the color explicitly i.e before calling dfs here is the code : Your text to link here...

And i got AC when I send the color along with dfs function Your text to link here...

if u look at both the codes dont u think they are equivalent? If not please tell me which edge case am i missing? Thanks in advance :)
