We have a string, "Hello World", which we want to reverse:The String to Reverse txt = "Hello World" [::-1] print(txt) Create a slice that starts at the end of the string, and moves backwards.In this particular
#return ''.join(string[len(string) - i] for i in range(1, len(string)+1)) return ''.join(string[i] for i in range(len(string)-1, -1, -1)) print(string_reverse1(string)) print(string_reverse2(string)) print(string_reverse3(string)) print(string_reverse4(string)) print(stri...
A sequence of non-space characters constitutes a word. Could the input string contain leading or trailing spaces? Yes. However, your reversed string should not contain leading or trailing spaces. How about multiple spaces between two words? Reduce them to a single space in the reversed string. ...

刚接触python不久,被python的简洁强大迷倒了,在做leetcode,Reverse words in a string时,刚开始还是传统的思路想着怎么处理空格问题一直测试不通过,写的很罗嗦被师弟吐槽说你写的代码好丑,好心塞。 废话不多说直接奉上思路代码: 翻转字符串如:"Hello I am echo",输出"echo am I Hello" ...

Input: "a good example" Output: "example good a" Explanation: You need to reduce multiple spaces between two words to a single space in the reversed string. Note: A word is defined as a sequence of non-space characters. Input string may contain leading or trailing spaces. However, your ...
White space is allowed in the string, and is simply ignored.很显然这个函数的作用就是将 str 字符数组以 base 指定的进制解读成数值并写入 rop 所指向的内存。该程序通过调用这个函数来实现数据的初始化赋值。之后调用的一个函数 __gmpz_powm 在文档中的定义是这样的:void mpz_powm (mpz_t rop, const ...
