... need to write a function which will detect if the input contains at least one value which is non-numeric. If a non-numeric value is found I will raise an error (because the calculation should only return a numeric value). The number of dimensions of the input array is not known in advance - the fun...

Other than that, for is just syntax sugar for the each method. When @collection is nil both loops throw an exce...

... The Fibonacci series is just one example of an exponential estimation scale. The reason an exponential scale is used comes from Information Theory. The information that we obtain out of estimation grows much slower than the precision of estimation. In f...
