I have the following list:
l = {{-5, -5, -5}, {-7, -5, -1}, {-9, -3, 15}, {-11, 1, 49}, {-13, 7, 0},
{-15, 15, 0}, {-17, 25, 0}, {-19, 37, 0}, {-21, 51, 0}, {-23, 67, 0}, {-25, 85, 0}}
I need to remove the items in the list that contain zero in the third item value. Finally I wish to obtain the following list:
{{-5, -5, -5}, {-7, -5, -1}, {-9, -3, 15}, {-11, 1, 49}}
