Application ID
In an online exam the test paper set is categorized by the letters A-Z. The students enrolled in the exam have been assigned a numeric value called application ID. To assign the test set to the student, firstly the sum of all the digits in the application ID is calculated. If the sum is within the numeric range 1-26 the corresponding alphabetic set code is assigned to the student, else the sum of digits is calculated again and so on until the sum falls within the range of 1-26.
Input 1: 6442
Output 1: P
Input 2: 558823
Output 2: D
