binary_string='1010001'# 定义输入的二进制字符串integer_value=int(binary_string,2)# 将二进制字符串转换为整数# 解释:int() 函数的第二个参数是基数,这里为 2,表示输入是二进制数 1. 2. 3. 步骤3: 将整数转换为对应的字符 接下来,我们可以使用 Python 的chr()函数将整数转换

Python Built-in Functions Python Basics Python bin() method converts a given integer to it’s equivalent binary string. If the method parameter is some other object (not integer) then it has to __index__() method (with double underscores on the both sides) which must return an integer ...

OK,因为是连续两个special binary string位置的交换,所以我们可以遍历S的每个位置,求出每个位置可能的special binary string,用map记录。接着交换任意两个连续位置的special binary string,取lexicographically最大的。不过这还不算完,注意:At the end of any number of moves,所以还需要迭代一波,直到max不再变化为止...

Binary Search in Python We can describe it like this: In computer science, abinary searchis an algorithm for locating the position of an item in a sorted array. The idea is simple: compare the target to the middle item in the list. If the target is the same as the middle item, you...
