Python

In Dax's theater, each chair is labeled with a letter followed by an integer. Given integers num$\_$rows and num$\_$columns, output the

label for each chair, followed by a space. End each row with a newline.

Ex: If the input is:

$3$

$5$

then the output is:

A$1$ A$2$ A$3$ A$4$ A$5$

B$1$ B$23$ B$4$ B$5$

$C1C2C3C4C5$

Note:

Rows are in alphabetical order. Chairs in the first row all start with the letter A$.$

Columns are in ascending order. Chairs in the first column all end with the integer $1.$

$,$ end$=")$ outputs $x$ without ending with a default newline.
