Here is a scenario
let’s say there are 5 notes/bills (rs10,rs20,rs50,rs100,rs200)
consider them to be of exact same size are stacked on one another and kept on a table such that only top note/bill can be seen
is there a way I can attach something to each note or a way using which I can find out the sequence in which the notes/bills are stacked without unstacking them
