Can someone help me why my code is giving me wrong output ?
By vishudon, history, 4 years ago, In English

I was trying to solve a problem, but I encountered a weird error. I don't know why my code is giving me wrong output. Can someone help me what is wrong in my code ? Thanks in advance.

Code

If I am giving this input : 

1 2
abc
cdf
edf

then my code is giving me this output : len1 = 2 , len2 = 2 ( while len1 must be 1 )

Note : If I am removing that common string checking part — these two lines ( line1 and line2 ) from 2nd for loop, then it is giving me correct output as len1 = 1 , len2 = 2

Please help me.

Seems like mp1[s]!=0 is creating new keys in the map.

      Yeah as scopeInfinity said mp1[s]!=0 adds another entry in the mp1 if s is not present already. Hence your len1 is 2 (For the given case).

      If you want to check if a string s is present map s or not then use mp1.find(s)!=mp1.end() Because map::find returns an iterator to the element if present otherwise its equal to mp1.end()
