Highest Occuring Character Send Feedback For a given a string(str), find and return the highest occurring character. Example: Input String: "abcdeapapqarr" Expected Output: ' a ' Since ' a ' has appeared four times in the string which happens to be the highest frequency character, the answer would be ' a '. If there are two characters in the input string with the same frequency, return the character which comes first. Consider: Assume all the characters in the given string to be in lowercase always. Input Format: lowercase always. Input Format: The first and only line of input contains a string without any leading and trailing spaces. Output Format: The only line of output prints the updated string. Note: You are not required to print anything explicitly. It has already been taken care of. Constraints: 0
