Given a string containing uppercase alphabets and integer digits (from 0 to 9), the task is to print the alphabets in the order followed by the sum of digits.
Input : AC2BEW3 Output : ABCEW5 Alphabets in the lexicographic order followed by the sum of integers(2 and 3).
Implementation: 1- Start traversing the given string. a) If an alphabet comes increment its occurrence count into a hash_table. b) If an integer comes then store it separately by summing up everytime. 2- Using hash_table append all the characters first into a string and then at the end, append the integers sum. 3- Return the resultant string.
Time Complexity: O(n)
