In this tutorial, we will see simple program to find frequency of characters in a string in java. There are multiple ways to solve this proble. Let’s see one by one. Table of Contents [hide] Using counter array
#include <bits/stdc++.h> using namespace std; void freq(string s) { //array to store frequency of 26 characters,initialized to 0 int arr[26] = { 0 }; for (int i = 0; i < s.length(); i++) { // s[i] is the ascii value of the letter at index i & 'a' //also ...
Given a string, sort it in decreasing order based on the frequency of characters. Example 1: Input: "tree" Output: "eert" Explanation: 'e' appears twice while 'r' and 't' both appear once. So 'e' must appear before both 'r' and 't'. Therefore "eetr" is also a valid answer. ...
