|
|

|
|
Welcome to Grains on Exercism's Rust Track.
|
||
|
|
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||
|
|
|
||
|
|
## Instructions
|
||
|
|
|
||
|
|
Calculate the number of grains of wheat on a chessboard given that the number on each square doubles.
|
||
|
|
|
||
|
|
There once was a wise servant who saved the life of a prince.
|
||
|
|
The king promised to pay whatever the servant could dream up.
|
||
|
|
Knowing that the king loved chess, the servant told the king he would like to have grains of wheat.
|
||
|
|
One grain on the first square of a chess board, with the number of grains doubling on each successive square.
|
||
|
|
|
||
|
|
There are 64 squares on a chessboard (where square 1 has one grain, square 2 has two grains, and so on).
|
||
|
|
|
||
|
|
Write code that shows:
|
||
|
|
|
||
|
|
- how many grains were on a given square, and
|
||
|
|
- the total number of grains on the chessboard
