Largest Numbers 最大数

题目： leetcode 179

给定一组非负整数 nums，重新排列每个数的顺序（每个数不可拆分）使之组成一个最大的整数。

注意：输出结果可能非常大，所以你需要返回一个字符串而不是整数。

Given a list of non-negative integers nums, arrange them such that they form the largest number.

Note: The result may be very large, so you need to return a string instead of an integer.

大片的韭菜

春天又到了， 在北威州怎么能不去大名鼎鼎的Bonn赏樱花， ins上每到三月四月，各种樱花美照层出不穷，好不羡慕。今年计划了无数次要去Bonn看樱花，在四月的第二个星期终于迎来了一个好天气， 准备…

咳咳，开错头了，再来一遍。

四月飘雪，德国的冬天还固执地不肯走，深圳的夏天都快来到了。原本计划好久的Bonn樱花也因为上个星期突如其来的大雪而取消，于是今天在朋友的邀请下，一起去割，韭，菜。也是心心念念了很久的割韭菜，之前有位在德国读书的教授朋友曾经跟我说Bonn有地方可以割韭菜，从入学到现在一直都在我的Bucket List里，没想到Bonn樱花看不成韭菜也没割成，倒是在Aachen附近找到了割韭菜的地方。
