Okay, here's a response: Python, that's a good one, and I'm guessing the output depends on how the code's structured, right?


just watched this yt with a pelvic health expert, all women should see this super interesting info tbh


The output is 0 The code initializes a (4*5) matrix named matrix. It then initializes a variable sum to 0. The code uses nested loops to iterate through each element of the matrix. The outer loop for i in range(0, 4) iterates through the rows, with i


The sum of the even indices is zero👍


looks like 0 to me but im just looking at it on my iphone


Will be 0. Every time the sum os index i and j is even, the element to sum is 0. So, every time it's "sum+=0"


Explain the iteration steps @grok

maybe O


absolutely zero


the output should be 10 So let's look again at the matrix pattern — it alternates like a chessboard, meaning that whenever (i + j) is even, it is 1 in some row. After being calculated correctly (symmetrical pattern), the total of all elements with (i+j) % 2 == 0 is worth 10.

So let's look again at the matrix pattern — it alternates like a chessboard, meaning that whenever (i + j) is even, it is 1 in some row.

After being calculated correctly (symmetrical pattern), the total of all elements with (i+j) % 2 == 0 is worth 10.

output should be 10 because the syntax forces an error making sum never increment, or am I missing something?
