CodeChefRating 2433Open on judge ↗

Given an array $A$ of $N$ integers. Consider an arbitrary **non negative** integer $X$(initially, **score is zero**). We will **sequentially** perform the following operation for indices $1,2,3,....N:$ For $i^{th}$ operation, - If $X = A_i$ then add $X$ to $score$. - Otherwise, assign $X := X \oplus A_i$. Where $\oplus$ is [bitwise **XOR**](https://en.wikipedia.org/wiki/Bitwise_opera
