Exercise: Sum All Elements of a Nested Array

Problem statement

In this challenge, we’ll use references and nested data structures to add all the elements of a two-dimensional nested array. The sum must be stored in a variable $sum.

Sample input

my @nested_array = ([qw(1 2)], [qw(3 4 5)], [qw(5 10)])

Expected output

30

Coding challenge

This is a simple problem related to references and nested data structure concepts we have covered. The input matrix has already been created. You must use it in your code and find the sum of all its elements.
