● run a loop for a from 0000 to 9999 and 9999 to 0000
● see (a+"").length() , if it is k, then add (4-k) zeores before printing a
//one more idea if not want to get into length(), Strings etc, just use conditions like <10, <100 & <1000 to know number of digits in number & add zeroes in front accordingly [but will become tiring work to write code if the pin will be of high number of digits so it would be better to make code working for any general number of digits].
