Show a nested loop which searches a two-dimensional array filled with random numbers uniformly distributed over 



[
1
,
…
,
20
]


{\displaystyle [1,\ldots ,20]}

.

The loops iterate rows and columns of the array printing the elements until the value 



20


{\displaystyle 20}

 is met.

Specifically, this task also shows how to break out of nested loops.
