# Answer mismatch for Problems Excel Sheet Column Number and Excel Sheet Column Title

• Ran the following code which are both accepted (Problem_Names: Excel Sheet Column Number and Excel Sheet Column Title) and yet there is an answer mismatch which should not be.
I also added the solution which I think was correct.
I might be wrong and missing something so please help.

``````string convertToTitle(int n)
{
string ans="";
int d = n;
while(d>0)
{
int int_ans=0;
char ch;
int_ans = d%26;
d = d/26;
if(int_ans==0)
{
d=d-1;
int_ans=26;
}
ch = char(int_ans+64);
ans = ch + ans;
}
return ans;
}
int titleToNumber(string s) {
int l= s.size(), n=0;
for(int i=0; i<l; i++)
n=n+(int(s[i])-64)*(pow(26, (s.size()-i-1)));
return n;
}
int main(){
for (int i=0; i<100; i++)
{
cout<<i<<":"<<convertToTitle(i)<<":"<<titleToNumber(convertToTitle(i))<<endl;
}
return 0;
}
``````

Correct solution according to me:

``````int titleToNumber(string s){
int l= s.size(), n=0;
for(int i=0; i<l; i++)
n=n+(int(s[i])-64)*(pow(26,(s.size()-i-1)))+i;

return n;
}``````
