already i have it to where it will return: max consecutive positive numbers :4
max consecutive negative numbers : 2
what i want it to return now is the value of the max consecutive positive numbers: 1+2+1+4 = 8 I want it to return 8
and for max consecutive negative numbers would equal -1+-9 = -10 so it would return -10
