Max occurring character is s. Time Complexity: O(n) Space Complexity: O(1) — Because we are using fixed space (Hash array) irrespective of input string size. Write a Python program to find the maximum occurring character in a given string. Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above. For example if input string is “test sample” then there are three characters with same and maximum count two i.e. 2. But if we know that our input string will have characters with value from 0 to 127 only, we can limit Hash array size as 128. First, we assigned -1 as the max value and declared the charFreq integer array of size 256. In this example, we will create a java program to count each character present in the string and find out the maximum and minimum occurring character in the given string. Space complexity. So the count for letter e will be stored in count[5] since e is at 5 th relative from character a. ... Then we iterate over the keys of the hash, which are the individual unique characters in the string. Example 2: Typically, ASCII characters are 256, so we use our Hash array size as 256. The string itself, its size. Function maxRepeating(char str[], int n) takes two input parameters. This specific implementation prints multiple characters if there are multiple characters in string with maximum … If more than one characters have the same count and that count is maximum then the If you want to have all the characters … STEP 1: START; STEP 2: DEFINE String str = "grass is greener on the other side" STEP 3: INITIALIZE minChar, maxChar. 1239. acknowledge that you have read and understood our, GATE CS Original Papers and Official Keys, ISRO CS Original Papers and Official Keys, ISRO CS Syllabus for Scientist/Engineer Exam, Remove duplicates from a string in O(1) extra space, Minimum insertions to form a palindrome | DP-28, Minimum number of Appends needed to make a string palindrome, Minimum characters to be added at front to make string palindrome, Rabin-Karp Algorithm for Pattern Searching, Optimized Naive Algorithm for Pattern Searching, Finite Automata algorithm for Pattern Searching, Pattern Searching | Set 6 (Efficient Construction of Finite Automata), Boyer Moore Algorithm for Pattern Searching, Boyer Moore Algorithm | Good Suffix heuristic, Aho-Corasick Algorithm for Pattern Searching, Z algorithm (Linear time pattern searching Algorithm), Check if a string is substring of another, Given two strings, find if first string is a subsequence of second, Find number of times a string occurs as a subsequence in given string, Given an array A[] and a number x, check for pair in A[] with sum as x, Find the smallest window in a string containing all characters of another string, Print a Binary Tree in Vertical Order | Set 2 (Map based Method), Count of unique pairs (arr[i], arr[j]) such that i < j, Count of same length Strings that exists lexicographically in between two given Strings, Write a program to reverse an array or string, Write a program to print all permutations of a given string.
