561. Array Partition I[easy] Given an array of 2n integers, your task is to group these integers into n pairs of integer, say (a1, b1), (a2, b2), ..., (an, bn) which makes sum of min(ai, bi) for all i from 1 to n as large as possible. Example 1: Inpu…
上一篇已经讲解过,array和slice的一些基本用法,使用array和slice时需要注意的地方,特别是slice需要注意的地方比较多.上一篇的最后讲解到创建新的slice时使用第三个索引来限制slice的容量,在操作新slice时,如果新slice的容量大于长度时,添加新元素依然后使源的相应元素改变.这一篇里我会讲解到如何避免这些问题,以及迭代.和做为方法参数方面的知识点. slice的长度和容量设置为同一个值 如果在创建新的slice时我们把他的长度和容量的值设置为样的值,那么在appen…
