You are given an array $A$ of size $N$. A partitioning of the array $A$ is the splitting of $A$ into one or more non-empty contiguous subarrays such that each element of $A$ belongs to exactly one of these subarrays. Find the number of ways to partition $A$ such that the parity of the sum of elements within the subarrays is alternating. In other words, if $S_i$ denotes the sum of the elements in
