### Re: Problem 013

Hi, I would like to know how they want us to write the answer. For instance if "azertyuiopa" are the first ten digits of the sum. Do they want us to write "azertyuiop" or "a.z.e.r.t.y.u.i.o.p"? or "a,z,e,r,t,y,u,i,o,p" or something else? My solution must be wrong but I prefere being sure. Thanks Fi...

Maybe, we should rethink our definition of easy, medium and hard problems

Right now, more people solved the "medium" Problem 240 in one week than the "easy" Problem 239 in two weeks
