Hi,

I need desperate help with building the algo. It seemed easy at first, but I am getting all confused.  Can anyone explain the step for calculation ?

Suppose the input is 4 digits, so that means I have to fill up 4 spaces with 9 digits(0-9) for each space and from the combinations, find the one that has equal sum for first 2 and last 2 digits.

If someone can help me with the steps, I think I can figure out the rest.

Thanks in advance.
