So basically want a program that would print the column name of google docs for example:-
Also, the input number can be a really large value eg the range can be up to long.

    function printColName(columnNumber){ ... return colName }

    printColName(4) => D
    printColName(27) => AA
    printColName(55) => BC

This is a very common problem and has appeared in multiple contests before. Check this problem.
Here is my code for reference-

Code 
#include<bits/stdc++.h>
#define ll long long int
#define fio ios_base::sync_with_stdio(false); cin.tie(NULL);
using namespace std; 
void fun(ll n)
{
	if(n>0)
	{
		n--;
		fun(n/26);
		cout<<char(n%26+65);
	}
}
void solve(){
     ll n;
     cin>>n;
     fun(n);
}
int32_t main()
{	
     fio;
    ll t=1;
    for(ll dd=1;dd<=t;dd++){
		solve();	
	}
}
