Thank you Sir, this was asked to me in one of interview.

long long int res, ans=INT_MIN;
vector<string> v;
s+=" ";
string s1="";
for(int i=0;i<s.size();i++)
{
if(s[i]==' ')
{
v.push_back(s1);
s1="";
}
else
s1+=s[i];

}

for(int i=0;i<v.size();i++)
{ res=0;
if(v[i][0]<65)
{
for(int j=0;j<v[i].size();j++)
{
if(v[i][j]==57)
{
res=0;
break;
}
else
{
res=res*10+v[i][j]-48;
}

}
}
ans=max(res, ans);
}
if(ans==0)
return -1;
return ans;
