There are 10 stacks of 10 coins each. 9 of the stacks contain coins that weigh 1g each. The other stack contains coins of 2g each. The coins look the same. We have a scale that we can get a measurement of grams from, not a balance. We can use the scale exactly once to weigh anything here from a single coin to all of them. How can we determine which stack is the 2g coins?

We have strings of format A_ _ _ _ _ _ _, an A followed by 6 spaces that can be a number 0-9. We also have regular expressions with the operations "or" and "*" defined as follows:. The easiest way to illustrate this is to give an example. "A000001 or A000000" has size 2 because it matches two strings. "*" represents a wild card, so A00000* has size 10 because it matches 10 different strings, (A000000 - A000009). "A0* or A1*" has size 20,000 because it matches 20,000 different strings. The question was this: Write a function that takes in a number N and outputs a regular expression that matches exactly N strings of format A _ _ _ _ _ _.
