The simplest of these algorithms is the [**Bubble Sort**](https://en.wikipedia.org/wiki/Bubble_sort), which is based on comparisons of elements two by two in a loop of passes through the elements. Your mission, if you decide to accept it, will be to input six whole numbers ramdonly ordered. Then implement the **Bubble Sort** principle to order these six numbers **using only loops and conditionals**.  \n",
