How to covert 2d string array to 2d integer array?

Question

suppose if give input as-
{"1","2","3"
"4","5","6"}
then output will be like-
{1,2,3
4,5,6}

Answer 1

Create an empty 2D array to receive the integers. Now, go through the original 2D array and then use Integer.parseInt(element_of_the_array) on each element and put the integers in the new array... This is for Java

In Python, you can do the same. You will just have to replace Integer.parseInt() by int(....)
