Excel Sheet Column Title\

Used the same strategy for breaking apart digits for this. Nothing too surprising.

Full Solution in Java:

 public class Solution {
    public String convertToTitle(int n) {
        StringBuilder sb= new StringBuilder();
        
        while(n!=0){
            int x = n%26;
            if(x==0){
                sb.append("Z");
                n-=26;
            }
            else{
                char c = (char)(x+64);
                sb.append(c);
            }
            n/=26;
        }

        return sb.reverse().toString();
    }
}
