#try to compile the file
gcc -lm main.c -o main

#if compile successful then go on
if [[ $? = 0 ]]; then
  #try to run program with time limite
  timeout 1s ./main < input.txt

  #if program run within the time then write result into output.txt file

    #if those are not same then result no

      echo "no" > result.txt
    fi
  #if program can not run within the time then result TE
  elif [[ $RV = 124 ]]; then
    echo "TE" > result.txt
