首先执行reverseString("abc"),这时候传入的str不为空,所以执行else部分。读到了reverseString(str.substr(1)),这时候就是递归调用,执行这段代码,其中str.substr(1)为"bc" reverseString("bc"),这时候传入的str不为空,所以执行reverseString(str.substr(1)),其中str.substr(1)为"c" reverseString("c"),这...
reverseString("bc"),这时候传入的 str 长度依旧不为 1,所以执行 reverseString(str.substr(1)),其中 str.substr(1) 为 "c" reverseString("c"),这时候传入的 str 长度为 1,所以执行 if 中的部分,返回传入的 str,也就是返回 "c" 回到reverseString("bc") 这一步,此时的 str[0] 为 "b"。由于上...

If yes, then the return value (a pointer) of the function has the same value as the input parameter s. If not, then the function must dynamically allocate memory for the C-string that it will return. In any case, the main purpose of homework is to learn by doing things yourself. It...

意思是 reverse这个函数的原型缺失 也就是说没有找到。reverse
Write a function that takes a string as input and reverse only the vowels of a string. Example 1: Given s = “hello”, return “holle”. Example 2: Given s = “leetcode”, return “leotcede”. Note: The vowels does not include the letter “y”. ...
(Make a function fun (char s). The function of the function is to reverse the contents of the string.) 编一个函数fun(char s),函数的功能是把字符串中的内容逆置。(Make a function fun (char s). The function of the function is to reverse the contents of the string.) It is only ...
