Strings have the following properties - A string consists of a fixed set of characters String position Default starts from 0th index The frequency of any character is the number of times it appears in the string. The frequency of any character can range from 0 (if it does not occur) to the length of the string. In this article, we will develop a code that takes a string as input and checks if the frequency of any character is equal to the sum of the frequencies of all other characters in the string. Let us look at the following example to better understand this topic Example Example 1 - str - "@!ab@!" Output - True For example, the following example string also contains special characters, where the corresponding frequency of each character is as follows - @=4! =2a=1b=1 cause

Course Introduction：Problem Statement We are given a positive integer num. We need to find a string consisting of lowercase letters such that the sum of all characters in the string is equal to num, and the string is the largest in lexicographic order. Here, ‘a’=1, ‘b’=2, ‘c’=3, ‘d’=4,…, ‘z’=26. We need to use "z" character at the beginning of the string to create the largest dictionary string. Finally, we need to use the last character based on the num%26 value. Example input num=30 and output ‘zd’ Explanation’s Chinese translation is: Explanation ‘zd’ is the largest lexicographic string with a character sum of 30 (z=26+d=4). Input 3 output ‘c’ Explanation
