给定一个包含红色.白色和蓝色,一共 n 个元素的数组,原地对它们进行排序,使得相同颜色的元素相邻,并按照红色.白色.蓝色顺序排列. 此题中,我们使用整数 0. 1 和 2 分别表示红色.白色和蓝色. 注意: 不能使用代码库中的排序函数来解决这道题. 示例: 输入: [2,0,2,1,1,0] 输出: [0,0,1,1,2,2] 进阶: 一个直观的解决方案是使用计数排序的两趟扫描算法. 首先,迭代计算出0.1 和 2 元素的个数,然后按照0.1.2的排序,重写当前数组. 你能想出一个仅使用常数空间…

  75. Sort Colors   给定一个具有红色,白色或蓝色的n个对象的数组,将它们就地 排序,使相同颜色的对象相邻,颜色顺序为红色,白色和蓝色. 这里,我们将使用整数0,1和2分别表示红色,白色和蓝色. 注意:  您不应该使用库的排序功能来解决此问题. 例: 输入: [2,0,2,1,1,0]输出: [0,0,1,1,2,2] 跟进: 一个相当直接的解决方案是使用计数排序的两遍算法.首先,迭代0,1,和2的数组计数,然后覆盖总数为0的数组,然后是1,然后是2. 你能想出一个只使用恒定空…

Given an array with n objects colored red, white or blue, sort them so that objects of the same color are adjacent, with the colors in the order red, white and blue. Here, we will use the integers 0, 1, and 2 to represent the color red, white, and bl…
