// Challenge: Concatenate Strings
// This coding challenge involves creating a C++ class template called strOps.
// The goal is to concatenate a variable number of strings using variadic
// templates and fold expressions, count the total number of characters in the
// concatenated string, and keep track of the total number of input strings.

// Key Concepts:
// 1. Utilizing variadic templates to accept a variable number of input strings.
// 2. Implementing fold expressions to efficiently concatenate strings.
// 3. Utilizing variadic variable templates to count the total number of input
