Description
Two Bases
题意翻译
给你一个 $n$ 进制 $a$ 位整数 $x$ 和一个 $m$ 进制 $b$ 位整数 $y$, 比较 $x$ 与 $y$ 的大小。 输入: 第一行分别为 $a$ 和 $n$; 第二行 $a$ 个数分别为 $x$ 从高到低每一位上的数的十进制形式; 第三行分别为 $b$ 和 $m$;第四行的 $b$ 个数分别为 $x$ 从高到低每一位上的数的十进制形式。 输出: 若 $x>y,$ 输出 `>`; 若 $x<y,$ 输出 `<`; 若 $x=y,$ 输出 `=`。题目描述
After seeing the "ALL YOUR BASE ARE BELONG TO US" meme for the first time, numbers $ X $ and $ Y $ realised that they have different bases, which complicated their relations. You're given a number $ X $ represented in base $ b_{x} $ and a number $ Y $ represented in base $ b_{y} $ . Compare those two numbers.输入输出格式
输入格式
The first line of the input contains two space-separated integers $ n $ and $ b_{x} $ ( $ 1<=n<=10 $ , $ 2<=b_{x}<=40 $ ), where $ n $ is the number of digits in the $ b_{x} $ -based representation of $ X $ . The second line contains $ n $ space-separated integers $ x_{1},x_{2},...,x_{n} $ ( $ 0<=x_{i}<b_{x} $ ) — the digits of $ X $ . They are given in the order from the most significant digit to the least significant one. The following two lines describe $ Y $ in the same way: the third line contains two space-separated integers $ m $ and $ b_{y} $ ( $ 1<=m<=10 $ , $ 2<=b_{y}<=40 $ , $ b_{x}≠b_{y} $ ), where $ m $ is the number of digits in the $ b_{y} $ -based representation of $ Y $ , and the fourth line contains $ m $ space-separated integers $ y_{1},y_{2},...,y_{m} $ ( $ 0<=y_{i}<b_{y} $ ) — the digits of $ Y $ . There will be no leading zeroes. Both $ X $ and $ Y $ will be positive. All digits of both numbers are given in the standard decimal numeral system.
输出格式
Output a single character (quotes for clarity): - '<' if $ X<Y $ - '>' if $ X>Y $ - '=' if $ X=Y $
