### Exercise 4: Checking Lexicographic Order in C++ In this task, you'll write a C++ program to read an input string from the user and determine if the string is sorted in lexicographically decreasing order. The solution must achieve this in linear time complexity. **Test Cases:** - Input Strings: `{"edcba", "pqtsr", "zgeba"}` - Expected Output: `{1, 0, 1}` **Explanation:** - The output is `1` if a string is lexicographically sorted in decreasing order, and `0` otherwise. - For example, "edcba" is sorted in decreasing order, so the output is `1`. - "pqtsr" is not sorted in decreasing order, so the output is `0`. - "zgeba" is sorted in decreasing order, so the output is `1`.
