Then we have to count the number of even numbers EL at the left of X and the number of even numbers ER at the right of X cause they will make the possible subarrays from main subarray. For the current main subarray the possible subarray count = (EL +1) * (ER+1).

One easy way to modify the algorithm to only use positive numbers is to append a whole lot of numbers at the start of the array. i.e. change 1,2,9,10,3,15 to -5,-4,-3,-2,-1,1,2,9,10,3,15. Then you can be sure that the optimal answer will never decide to make the 1 go negative because it would cost so much to make all the negative numbers smaller.
