Braille

Report a typo

The Braille system is a tactile writing system for people who lost their sight. Instead of letters and numbers, it uses braille cells.

Here is how hello world looks in Braille:

Hello world  in Braille

A whole braille cell consists of six dots arranged in two columns, each column having three dots. Each dot can be either raised () or not. Can you find the maximum number of braille cells in the system that can carry a meaning?

To solve this task, imagine that each dot in a single braille cell is a binary digit (it can have only one of two values – raised or not raised), and find the maximum binary number that consists of six bits. Provide the answer in decimal.

A blank Braille cell or no dots is not a meaningful symbol in Braille. Instead, it represents whitespace or the lack of content. Therefore, it doesn't count.
