Sum of Every Second Row
0
Given a 2D tensor (matrix) `matrix` as input, return a tensor that has sum of all elements in rows 0, 2, 4,...
To solve this exercise, extract every second row from the given matrix using slicing with a step of 2. Then, compute the sum of each row to get the result.Examples:
