@Dave: Still your approach to solve the problem remains correct. (subtracting a number from max possible value & then comparing this difference with another number). So, no need to think that you were brain dead (If you were, you would have posted a movie story here)..[?] Mathematically it is wrong, not in terms of approach..[?]
