Question

You don't need to read input or print anything. Your task is to complete the function reverseWords(string s) which takes the string S as input and returns the resultant string by reversing all the words separated by dots.

Attached are the given Driver Codes examples of what the program should do.

### Example 1: **Input:** S = "i.like.this.program.very.much" **Output:** i.ekil.siht.margorp.yrev.hcum **Explanation:** The words "i", "like", "this", "program", "very", "much" are all reversed. --- ### Example 2: **Input:** S = "pqr.mno" **Output:** rqp.onm **Explanation:** Both "pqr" and "mno" are reversed. --- These examples demonstrate how to reverse each word in a string while keeping the words separated by periods. The transformation involves taking each segment between the periods and reversing its characters.

```cpp // { Driver Code Starts #include<bits/stdc++.h> using namespace std; // } Driver Code Ends class Solution { // Function or method implementations will go here }; // { Driver Code Starts. int main() { int t; cin >> t; while (t--) { string s; cin >> s; Solution ob; cout << ob.reverseWords(s) << endl; } return 0; } ``` ### Explanation for an Educational Website: This code is written in C++ and demonstrates the basic structure for solving a problem in competitive programming. The file begins with necessary `#include` directives to import standard C++ libraries and the namespace `std`. This allows the use of standard input and output functions without prefixing them with `std::`. #### Structure: 1. **Class Definition:** - `class Solution`: This defines a class named `Solution`. The body of the class is currently empty, represented by `{}`. Typically, this class would contain methods to solve specific problems, such as reversing words in a string. 2. **Main Function:** - The `main()` function is the entry point of the program. - It starts by declaring an integer `t` to store the number of test cases. - It then reads the value of `t` using `cin >> t;`. - A `while` loop runs `t` times to handle each test case. - For each iteration, it reads a string `s`. - An instance of `Solution`, `ob`, is created. - It calls a supposed method `reverseWords` on `ob` with `s` as an argument and prints the result using `cout`. This code is a template, commonly used in programming contests, where you substitute the functionality of the `Solution` class with logic to handle the problem statement—in this case, a hypothetical method `reverseWords` that would reverse the words in the input string.
