I am still a bit confused about the expected output for the calculate_min_energy_column() function in this test which is “expected min energy column index 1”, but when I look at the values at index 1 the value is zero but at index 0 it is also 0 and in the project presentention video the figure 8 showed how the leftmost pixel is selected and not the one to the right of it.

Thanks, I see my fault I returned index 11 but that is the index of the row and the column, but we only want the column index so of course I have to stripe the second “1” because that is the row index
