Question

输出字符串

public static void main(String[] args) {
        String s = "Let's take LeetCode contest";
        System.out.println(reverseWords(s));
//        reverseWords(s);
    }

    public static String reverseWords(String s) {
        String sArr[] = s.split(" ");
        String str = "";
        for (int i = 0, j = 0; i < sArr.length; i++) {
            String c = reverseString(sArr[i].toCharArray());
            str = str + c + " ";
        }
        return str;
    }

    public static String reverseString(char[] s) {
        int left = 0;
        int right = s.length - 1;
        while (left < right) {
            char temp = ' ';
            temp = s[left];
            s[left] = s[right];
            s[right] = temp;
            left++;
            right--;
        }
        return s.toString();
    }
