Hi, here's your problem today. This problem was recently asked by Amazon:
MS Excel column titles have the following pattern: A, B, C, ..., Z, AA, AB, ..., AZ, BA, BB, ..., ZZ, AAA, AAB, ... etc. In other words, column 1 is named "A", column 2 is "B", column 26 is "Z", column 27 is "AA" and so forth. Given a positive integer, find its corresponding column name.

Output: AZ
Input: 676
Output: YZ
Input: 702
Output: ZZ
Input: 704
