A Bingo card is five columns of five squares each, with the middle square designated "FREE". Numbers cannot duplicate.
The five columns are populated with the following range of numbers:
In as few characters as possible, output a string that can be interpreted as a randomized Bingo card. For example:
This example is not randomized so that I can show that column 1 is populated with 1,2,3,4,5. Also note that the free space has not been given any special treatment because the front-end that interprets this string will skip it.
Another example would be:
In this example, the output is by row instead of by column.
A third example might be:
This is the same output as the 1st example except in fixed length.
