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....
Given a string and we have to find the frequency of each character of the string in Python.ExampleInput: "hello" Output: {'o': 1, 'h': 1, 'e': 1, 'l': 2} Python code to find frequency of the characters# Python program to find the frequency of # each character in a string ...
