Random Question about possibility to create a simulation

I found this to be an interesting question - so I decided to explore it a bit.

Here is what I managed to come up with.

As Rod stated - we will need a text entry box for the participant to enter some characters.

This TEB is set to a variable - in my case - called  myPass

I have some JavaScript placed onEnter to the slide to help prep things for the validation.

// declares a variable called checkPass to later use as an array
var checkPass

// This array stores the various values we will accept as a special character
var specials = ["<",">","@","!","#","$","%","^","&","*","(",")","_","+","[","]","{","}","?"];

// This function checks to see if the password meets our criteria and resets the flags
function verify() {
if (num + spec + upper + lower == 4) {
console.log("Valid Password");
}
else {
console.log("Invalid Password");
}
num=0;
spec=0;
upper=0;
lower=0;
}

// This function checks each type in order of number, special, upper, and lower case
function checkCase(item) {
   if (!isNaN(item * 1)) {
      console.log(item + " is numeric");
      num = 1;
      }
    else if (specials.includes(item)==true) {
         console.log(item + " is special");
         spec = 1;
      }
    else if (item == item.toUpperCase()) {
         console.log(item + " is upperCase");
         upper = 1;
      }
    else if (item == item.toLowerCase()) {
         console.log(item + " is lowerCase");
         lower = 1;
      }  
}

Then we have some JavaScript on the button to check to run things.

// This splits what the leaerner entered into individual characters for examination
// Values are placed into the checkPass array
checkPass = myPass.split("");

// For every item in the checkPass array - run the checkCase function
checkPass.forEach(checkCase);

// in a half second - check if the password meets criteria
// This allows time for the function checks on the password to complete.
setTimeout(verify, 500);

I chose to log to the console to verify all was working as you can see below but you could have whatever else happen instead.

If I change one to be capital (the W) - it returns valid.

Do you mean something like this:
