Implement function q5(L) that takes as input a (possibly empty) list of (possibly empty) lists of numbers and returns a three-element list. The first element is a list of the sums of corresponding lists in L, the second element is the number of lists in L that contain more positive than negative values, and the third element in the minimum value among all items in all lists (or None if there is no minimum). Note: you may NOT use Python's 'sum' or 'min' function (instead,compute sums and min within a loop or loops.) For example, >>> q5([[1, 2, 2], [3]]) [[5, 3], 2, 1] >>> q5([[0, 1, 0], [], [-1, 100]]) [[1, 0, 99], 1, -1]
