Let's define the "unwrapped size" function `u` of a nested list `l` (containing only lists) by the following rules:
* If `l` is empty, then `u(l)` is 1.
* If `l` is non-empty, `u(l)` is equal to the sum of the unwrapped sizes of every element in `l`, plus one.
Your task is to write a program (or functi... |

There is a well known question [here](https://codegolf.stackexchange.com/questions/85/fibonacci-function-or-sequence) that asks for a short (least characters) fibonacci sequence generator.
I would like to know if someone can generate the first N elements only, of the fibonacci sequence, in very short s... |

# Introduction
The Cartesian product of two lists is calculated by iterating over every element in the first and second list and outputting points. This is not a very good definition, so here are some examples: the Cartesian product of `[1, 2]` and `[3, 4]` is `[(1, 3), (1, 4), (2, 3), (2, 4)]`. The pr... |

Let's say I have a non-empty list (array):
```
l = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
```
I want to incrementally slice the list into incremented amount of elements per chunk.
For this array, my desired output is:
```
[[1], [2, 3], [4, 5, 6], [7, 8, 9, 10]]
```
What would be the best way to slice the arra... |

## Challenge:
Given the input number `n`. It should give me nested sublists of `n` layers with the [power of two](https://en.wikipedia.org/wiki/Power_of_two) numbers for each level. Each power of two value will be in separate sublists.
## Notes:
* `n` will always be greater than 0
* I am using the exam... |

Given a sequence of three integers, determine if the sequence is arithmetic (of the form `[a, a+d, a+2*d]`) or geometric (of the form `[a, a*r, a*r^2]`) by outputting a fourth term that completes it (`a+3*d` for arithmetic, `a*r^3` for geometric).

## Background
You have been given the task of calculating the number of landmines in a field.
You must calculate the landmine score given a list/string of numbers and the landmine number.
The landmine number tells you where landmines are.
For each digit:
1. if the left digit plus the right digit is equ... |
