请问算法把这个转换怎么写

Question

把这个字符串God Skin 转换成 doG nikS 有没有会写这个简单的算法的

Answer 1

#include <stdio.h>
#include <ctype.h>

void swap(char *p, char *q)
{
    char t = *p;
    *p = *q;
    *q = t;
}

void reverse_impl(char *first, char *last)
{
    while (first < last)
        swap(first++, --last);
}

void reverse(char *s)
{
    while (*s)
    {
        char *p = s;
        while (*p && isblank(*p))
            p++;
        char *q = p;
        while (*q && !isblank(*q))
            q++;
        reverse_impl(p, q);
        s = q;
    }
}

int main(int argc, char *agv[])
{
    char s[] = "God Skin";
    reverse(s);
    printf("%s\n", s);
    return 0;
}

$ gcc -Wall main.c
$ ./a.out
doG nikS
