Given a string, determine if it is an int, a float or neither.
Examples
123 - int
62727.0033 - float
644c.33 - neither
Your code should output a different value depending on which it is. For example it could return "i" for int, "f" for float and "n" for neither.

The following are floats...
In this challenge you will take two lists as input and you will zip them. The zip can be defined with this recursive expression:
\$
\mathrm{zip}(a,b) = \begin{cases}
\left[\,\,\right] & a = \left[\,\,\right] \\
[a_0,\mathrm{zip}(b, \mathrm{tail}(a))] & a \neq \left[\,\,\right]
\end{cases}
\$

Given an array of numbers as input, find all permutations that do not have the same number next to each other, then print them all out. If no permutations were found, print "Nothing". Note that the original array can be a permutation.
Test cases:
[0, 1, 1, 0] -> [1, 0, 1, 0], [0, 1, 0, 1]
[0, 1, ...
