Given a string, and we have to swap all characters using python program.If you are provided with a string, return a new string such that the first and the last characters have been exchanged. Also, you should consider the following cases:...
In a string composed of ‘L’, ‘R’, and ‘X’ characters, like “RXXLRXRXL”, a move consists of either replacing one occurrence of “XL” with “LX”, or replacing one occurrence of “RX” with “XR”. Given the starting string start and the ending string end, return True if ...

Given a binary string s, return the minimum number of character swaps to make it alternating, or -1 if it is impossible.The string is called alternating if no two adjacent characters are equal. For example, the strings "010" and "1010" are alternating, while the string "0100" is not....
Swapping any two characters results in S remaining aaaaa. Thus, only one string can result from the operation. 组合数,先总数也就是n*(n-1)/2 ,因为有相同的就要减去相同的时候交换的次数。 但是最后还要判断same的数量最后res++, 错就错在这里了。
