man love your explanation thanks for this much mehnaat :)

[@i.vigneshdavid1698]

Thank you guys. Hardest thing in every language is regex...

[@saiyashwanth1991]

few suggestions could be naming convention, since you are coding in java better to go with camelCasing. So code looks more clean ,interviewer also focus on coding standards besides our working solutions.

Point taken !!

for those who are searching for c++ solution class Solution { public: bool isNumber(string s) { bool digit=false,dot=false,seene=false; int count=0; for(int i=0;i0 && (s[i-1]!='e' && s[i-1]!='E'))return false; if(i==s.size()-1)return false; count++; } else if(ch=='.'){ if(dot || seene)return false; if(i==s.size()-1 && digit==false)return false; dot=true; } else if(ch=='e'|| ch=='E'){ if(seene)return false; if(digit==false || i==s.size()-1)return false; seene=true; }else{ return false; } } return true; } };

And this shitty question, Ladies and Gentlemen, is one of the top asked questions at Meta 🙄.

All the more reason to learn it. Thanks
