There have been few questions which have down-votes more than the up-votes. There could be various reasons for it. In some cases, questions are confusing or examples are not good or it could be that problem is really a math formula and not a coding problem. Anyways it would be great if such problems will not be included in monthly challenge

So far 2 out 3 questions in July challenge have higher down-votes

Arranging Coins -

Prison Cells After N Days -
