剑指 Offer 58-II左旋转字符串

思路

还是遍历,先遍历k到strlen(s)的,放到res里,之后再把0到k的接在后面就ok了

char* reverseLeftWords(char* s, int n) {
    int len = strlen(s);
    char* res = (char*)malloc(len + 1);
    int index = 0;

    for (int i = n; i < len; i++) {
        res[index++] = s[i];
    }

    // 将前 n 个字符添加到 res
    for (int i = 0; i < n; i++) {
        res[index++] = s[i];
    }

    res[index] = '\0';
    return res;
}
