Finding the frequency of a character in a stringHere, we are reading a character array/string (character array is declaring with the maximum number of character using a Macro MAX that means maximum number of characters in a string should not more than MAX (100), then we are reading a ...
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. ...
