| * In JS, we can write bits by using prefix `0b`. | |
| * In this example, bits are separated by a space just to make | |
| * it simple to apply grid reading. | |
| * | |
| * Grid Reading means picking one column at time and reasoning only | |
| * on that column. This will be helpful in the article. | |
| * | |
| * Please, also note that in JS, 0b numbers can use up to 32 bits (2^32 = 4294967296). | |
