Problem 4: Character Frequency (10 points) Develop an algorithm that loops through a given string S and returns the character that occurs most frequently. You can assume S contains at least 2 characters and only contains lowercase letters in the English alphabet. If there are more than one characters with the highest frequency, return the character that occurs first in the string. Example output S "abcaadddb" Return: 'a Note: while both 'a' and 'd' occur 3 times, we return 'a' because it occurred first in the string
