5
3

```

Example 2:

 `# Julia program to illustrate ``# the use of first() method``  ` `# Getting the first element of ``# the specified 2D and 3D array``println(first([``3` `5``; ``7` `9``]))``println(first([``"a"` `"b"``; ``"c"` `"d"``]))``println(first(cat([``1` `2``; ``3` `4``], [``5` `6``; ``7` `8``], ``                  ``[``2` `2``; ``3` `4``], dims ``=` `3``)))``println(first(cat([``"a"` `"b"``; ``"c"` `"d"``], ``                  ``[``"e"` `"f"``; ``"g"` `"h"``], ``                  ``[``"i"` `"j"``; ``"k"` `"l"``], dims ``=` `3``)))`
