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...

Reverses the given string str. The function preserves letter cases and white spaces. For example, the reverse string of "the" is "eht", and "Here I am" is "ma I ereH". Version 1: voidreverseString(char*str){if(str==NULL)return;char*sp=str;intlen=0;while(*sp!='\0'){len++;s...
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...
functionreverseString(str){returnstr.split('').reverse().join('');} 解释: .split 返回分割后的数组,因此可以直接调用 .reverse .reverse() 方法返回的是翻转后的数组,因此可以直接调用 .join .join 之后就是我们想要的字符串,直接返回即可 这里用到了 Method Chaining,也就是方法的链式调用。只要你熟悉方...
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...

So the main function should looks like this: let data =["p","r","e","f","e","t","","m","a","k","e","","p","r","a","t","i","c","e"]; function main(_data) { let data=_data.slice(); reverseWholeString(data); ...
