Problem 44676. Mean = Standard Deviation

Created by Mehmet OZC

Solve Later

Create a series with following properties;

All of the members should be positive integer
Mean of the series should be integer
Standard deviation of the series should be integer (use a normalization factor of N instead of N-1)
Mean should be equal to standard deviation

For example if input is 6, you can return the following series;

out = [12 44 2 24 2 6]

mean(out) = 15;
std(out,1) = 15;

Another example; if input is 4, a possible solution;

out = [24 2 2 48];
mean(out) = 19;
std(out,1) = 19;

zeros(x,1) is not an acceptable solution. A new assert line added and all solutions are rescored

I was wondering what the one line command was to do this when I saw the scores as low as they were!! Those were before the all(y>0) condition was added.

haha! I was discussed this one with binbin yesterday, he said this one was ill-conditioned, sooner or later will be fixed. We submit a solution anyway, sort of for fun. hope you don't mind it. But if really do that can be tricky indeed. good problem.
