Title Blank Replace Problem Given a string arguments, define the recursive function blankReplace(), which replaces all instances of the dash character \"-\"found within s with the blank space character \"\". As examples, a call to blankReplace(\"Test- Example\") will return the string \"Test Example\", while a call to blankReplace(\"133-Exam-1-Study-Guide\") will return \"133 Exam Study Guide\" In a given recursive call, the current substring's last character will be concatenated to a smaller instance of blankReplace(). If this last character is not a dash, then it will be concatenated to a smaller instance of blankReplace(); otherwise, a blank space will be concatenated to this smaller instance. The function's base case occurs once the smallest possible non-empty string, a single character, is returned. This function terminates by returning the complete string back to the calling function with all dashes replaced by blank spaces. Your recursive function should have a std::string return type, so you will need a way to ensure that your base case is returning a single character string literal, not a character literal. You are welcome to try to_string() to see what kinds of issues its usage string, a single character, is returned. This function terminates by returning the complete string back to the calling function with all dashes replaced by blank spaces. Your recursive function should have a std::string return type, so you will need a way to ensure that your base case is returning a single character string literal, not a character literal. You are welcome to try to_string() to see what kinds of issues its usage creates. As a courtesy, recall that character positioning in strings is zero-based. Implementation Your definition must adhere to the following requirements: blankReplace() correctly, recursively returns the string arguments with each dash character \"-\" replaced with the blank space character\". (4 points) Characters must be added to the a recursively-returned string using the addition operator (+) or equivalent. Characters must be added to the a recursively-returned string using the addition operator ( + ) or equivalent. (2 points) Your recursive definition must not use any loops (e.g. for loops, while loops, do-while loops, ranged for loops, etc.), under any circumstances. (2 points) Results To verify your work, you are provided with the following main() function: int main() cout cout
