{"problem":"Let $x_0,x_1,x_2,\\dotsc$ be a sequence of numbers, where each $x_k$ is either $0$ or $1$. For each positive integer $n$, define \n\\[S_n = \\sum_{k=0}^{n-1} x_k 2^k\\]\nSuppose $7S_n \\equiv 1 \\pmod{2^n}$ for all $n \\geq 1$. What is the value of the sum  \n\\[x_{2019} + 2x_{2020} + 4x_{2021} + 8x_{2022}?\\]"}
