Need help on a simple basic JavaScript

[chaminda]

Hello guys.

I need to know how can i write a script to read 20 numbers within 10 - 100 range and print it only if it is not an duplicate of a number that has already been read. I need to do this with only using a single one dimensional array .currently my script is as follows

<script type="text/javascript">
//creating an array which hold the 20 numbers
myArray = ["22","32","43","54","65","76","87","98","19","25","11","12","13","14","15","16","17","18","19","22"];
var flag = 0;
for (var i = 0; i < myArray.length; i++)
{
if (flag != myArray[i])
        {
                document.write(myArray[i] + " ");
                flag = myArray[i];
                        
        }

}
</script>

The problem with this script is the flag variable dose not hold the all previous values. anyway to do this using a single one dimensional array?

I won't go into too much detail, since this looks like a homework assignment, but there's at least two ways to do this:

1.) Sort the array (myArray.sort()) before the loop. This way, it's ok to only compare to the last printed value.

2.) Put a second loop within the main loop in order to compare the current value to all the previous values.
