{"answer_type":"Numerical","is_multiple_answer":false,"language":"English","question":"For a sequence $x_{1}, x_{2}, \\ldots, x_{n}$ of real numbers, we define its price as\n\n$$\n\\max _{1 \\leqslant i \\leqslant n}\\left|x_{1}+\\cdots+x_{i}\\right|\n$$\n\nGiven $n$ real numbers, Dave and George want to arrange them into a sequence with a low price. Diligent Dave checks all possible ways and finds the minimum possible price $D$. Greedy George, on the other hand, chooses $x_{1}$ such that $\\left|x_{1}\\right|$ is as small as possible; among the remaining numbers, he chooses $x_{2}$ such that $\\left|x_{1}+x_{2}\\right|$ is as small as possible, and so on. Thus, in the $i^{\\text {th }}$ step he chooses $x_{i}$ among the remaining numbers so as to minimise the value of $\\left|x_{1}+x_{2}+\\cdots+x_{i}\\right|$. In each step, if several numbers provide the same value, George chooses one at random. Finally he gets a sequence with price $G$.\n\nFind the least possible constant $c$ such that for every positive integer $n$, for every collection of $n$ real numbers, and for every possible sequence that George might obtain, the resulting values satisfy the inequality $G \\leqslant c D$.","question_type":"Open-ended","subject":"Math"}
