@[wangbw](/space/show?uid=39541) k的初始值在哪里
by andyli @ 2018-07-21 10:27:10
@[wangbw](/space/show?uid=39541) `ans[k++]+=a[i];`应该改成`ans[k++]=a[i]`

@[wangbw](/space/show?uid=39541) 还有您不需要写cmp，调用sort时直接这样：`sort(ans, ans+k);`就可以了
by andyli @ 2018-07-21 10:29:47
@[wangbw](/space/show?uid=39541) `a[i][idx]==s[0]`这样判断有问题
应改成`idx==0&&a[i][idx]==s[0]`

已经AC，感谢:)

@[wangbw](/space/show?uid=39541) 刚刚我讲错了，应该是`idx==0&&a[i].substr(idx, s.length())==s`

@[wangbw](/space/show?uid=39541) 不谢
