建议把flag定义在最外层for中。

每次循环开始时要将flag初始化为1

@[suyeyue](/space/show?uid=141654) flag=1定义在for循环里面，查找有没有重复时i和j不能相等QAQ
by 自闭头铁娃 @ 2018-11-02 17:17:26
@[suyeyue](/space/show?uid=141654) 等等不行QAQ有输出但不能AC
by 自闭头铁娃 @ 2018-11-02 17:18:19
@[一只废柴墨](/space/show?uid=100967) 有输出就可以调了，刚入门就要多调
by 无限UCW @ 2018-11-02 17:19:16
@[无限UCW](/space/show?uid=88280) QAQ好像是
