#152111 - Interesting interview problem
I set this problem for a guy who I was interviewing the other day, not necessarily to see if he could solve it but how he went about trying to solve it, you might know the answer so don't answer right away let see who can solve it:-
You have two peices of string not necessarily the same length or thickness and if you burn them they both burn in a non-linear way,they might burn half the length in 1 second and the rest in 59 minutes and 59 seconds,they might not.The only thing that can be said about them is that they both burn from one end to the other in exactly one hour. The problem is to accurately measure 45 minutes by burning the peices of string.
