Write a script called createdirfile.sh that creates a directory or a file that does not exit. The script will provide the choice to create a directory or a file, and get the directory name or file name to create. The script needs to use functions. Here is the structure of the script suggested for you:

# script header

createDir(){

}

createFile(){

}

#main

# Prompt for inputs

# if to create directory, check if the directory already exits. If not, call the createDir function, otherwise, # display an error message

# if to create file, check if the file already exits. If not, call the createFile function, otherwise, # display an error message
