rotate string

rotate string

1. Problem Description
   Given a string (in the form of a character array) and an offset, rotate the string in place from left to right according to the offset.
   2. Problem example
   Input str = "abcdefg", offset=3, output "efgabcd".
   Input str = "abcdefg", offset=0, output "abcdefg".
   Input str = "abcdefg", offset=1, output "gabcdef".
   3. Code implementation

class Solution:
    #参数s:字符列表
    #参数offset：整数
    #返回值：无
    def rotateString(self,s,offset):
        if len(s)>0:
            offset = offset % len(s)
        temp = (s + s)[len(s) - offset:2 * len(s) - offset]
        for i in range(len(temp)):
            s[i] = temp[i]
#主函数
if __name__ == '__main__':
    s = ["a","b","c","d","e","f","g"]
    offset = 3
    solution = Solution()
    solution.rotateString(s,offset)
    print("输入：s=",["a","b","c","d","e","f","g"],"\n\t","offset = ",offset)
    print("输出:s=",s)

Adjust the main function:

if __name__ =='__main__':
    solution = Solution()
    s=list(input("输入：s="))
    offset = int(input("offset="))
    solution.rotateString(s,offset)
    print("输出:s=", s)
