You can do the following operation on an array A any number of times: - Select two indices, $1\leq l \leq r \leq |A|$ where $|A|$ is the size of array A. - For each $l\leq i \leq r$ , assign $A_i:=A_i \oplus (i-l+1). ^{\dagger}$ Define a binary function $F$ on an array $A$, where: $$ F(A) = \begin{cases} 1 & \text{if it is possible to make all elements of } A \text{ equal after any number
