• 九度oj 题目1135:字符串排序


    题目描述:

    先输入你要输入的字符串的个数。然后换行输入该组字符串。每个字符串以回车结束,每个字符串少于一百个字符。
    如果在输入过程中输入的一个字符串为“stop”,也结束输入。
    然后将这输入的该组字符串按每个字符串的长度,由小到大排序,按排序结果输出字符串。

    输入:

    字符串的个数,以及该组字符串。每个字符串以‘ ’结束。如果输入字符串为“stop”,也结束输入.

    输出:

    可能有多组测试数据,对于每组数据,
    将输入的所有字符串按长度由小到大排序输出(如果有“stop”,不输出“stop”)。

    样例输入:
    5
    sky is grey
    cold
    very cold
    stop
    3
    it is good enough to be proud of
    good
    it is quite good
    样例输出:
    cold
    very cold
    sky is grey
    good
    it is quite good
    it is good enough to be proud of
