Execution with Input and Output Files

To run the compiled C++ program with input from a text file and store the output in another text file, follow these steps:

1. Compile the C++ file:

   g++ <path_to_cpp_file> -o <output_executable_name>

   Example:

   g++ ./codeforces_sol.cpp -o ./codeforces_sol

2. Run the program with input and output redirection:

   <output_executable_name> < <path_to_input_file> > <path_to_output_file>

   Example:

   ./codeforces_sol < ./input.txt > ./output.txt

   This will run the program with input.txt as the input file and save the output to output.txt.
