{
    "shell_cmd": "g++ \"${file}\" -o \"${file_path}/${file_base_name}\"",
    "file_regex": "^(..[^:]*):([0-9]+):?([0-9]+)?:? (.*)$",
    "working_dir": "${file_path}",
    "selector": "source.c, source.c++",
    "variants":
    [
        {
            "name": "Run",
            "shell_cmd": "g++ -O2 -static -Wno-unused-result -std=c++17 -DONLINEJUDGE \"${file}\" -o \"${file_path}/${file_base_name}\" && \"${file_path}/${file_base_name}\""
        }
    ]
}

Almost done!

3 . Now Save this file and remember the name of the file it will need in step 7 . and the file extension will be .sublime-build

       freopen("input.txt","r",stdin); //can need to change file . this one for taking input
       freopen("output.txt","w",stdout); // this one for output
  #endif

       //Your Code

  #ifdef ONLINEJUDGE
     fprintf(stderr, "\n>> Runtime: %.10fs\n", (double) (clock() - tStart) / CLOCKS_PER_SEC); // this line gives your code runtime
  #endif
