==Problem statement== The problem is ambiguous as stated. It says to climb one step up, not climb up one step up from the starting position. Thus the original C# code that was there solved the 'climb one step up'. —Preceding unsigned comment added by [[Special:Contributions/|]] :Okay, I've made it more explicit. —[[User:Underscore|Underscore]] 00:30, 7 November 2009 (UTC)
