// Solution 1: An interesting problem. As the elements are all integers, if not encountering 0, the absolute value of the product will continue to increase. Thus the product is either min or max. By keeping watch over both ends, we have the maximum product of subarrays. This holds only...
The array may contain multiple peaks, in that case return the index to any one of the peaks is fine. You may imagine thatnum[-1] = num[n] = -∞. For example, in array[1, 2, 3, 1], 3 is a peak element and your function should return the index number 2. Your solution should...
