Project Euler Problem 1,2,3,4,5 in Java NOTE : Don't look at the solution if you had not tried it yourself. Because real learning is an active process and seeing how it is done is a long way from experiencing that epiphany of discovery.So you try possible solution but something doesn't work and it's hours now when that could be done in minutes. There is nothing wrong in looking at the solution if you have been doing it for long and couldn't figure it out. After looking the solution you may realize what bit of changes you could do for better result. It might be something very silly or stupid thing that you forgot and it's very frustrating.No matter how frustrating problems are, there is almost certainly a solution out there on web. These are my attempts or solution to the problems it might be simple or complex depending on how well you understand my algorithm. I have solved each problem using Java. It took me less than hour in some problems to design efficient ...
