String Run-Length Encoding Count

Problem Statement

String Run-Length Encoding Count Problem Description You are given a Java program that takes a string as input. The program implements a variation of Run-Length Encoding (RLE) where it calculates the frequency of consecutive characters but outputs only the counts of those characters, omitting the characters themselves. Your task is to understand the code logic provided below and determine the output for a given input string. The algorithm iterates through the string, counting consecutive occurrences of the same character. When the character changes, the accumulated count is appended to the result string, and the counter resets for the new character. Finally, the count of the last character sequence is appended. The provided code snippet performs the following steps: Reads an input string. If the string is null or empty, it returns an empty string. It traverses the string, keeping a running count of identical consecutive characters. It concatenates these counts into a single output stri
