logical deduction - Interview Question or Pathbreaking puzzle


I thought this changes the way series of numbers are looked at



1 
1 1
2 1

Write down the next three lines



Answer



The answer is this:



111221

312211
13112221






The first number specifies the quantity of digits of the set above it and the second number specifies what the digit is. The second line is 11 it is saying that the line above it is one one. The third line states that the line above it is two ones. The fourth line is saying there is one two and one one.
