In an array of integers, a "peak" is an element which is greater than or equal to the adjacent integers and a "valley" is an element which is less than or equal to the adjacent integers. For example, in the array {5, 8, 4, 2, 3, 4, 6}, {8, 6} are peaks and {5, 2} are valleys. Given an array of integers, sort the array into an alternating sequence of peaks and valleys.
\r\n\r\nExample:
\r\n\r\n\r\nInput: [5, 3, 1, 2, 3]\r\nOutput: [5, 1, 3, 2, 3]\r\n\r\n\r\n
Note:
\r\n\r\nnums.length <= 10000在一个整数数组中，“峰”是大于或等于相邻整数的元素，相应地，“谷”是小于或等于相邻整数的元素。例如，在数组{5, 8, 4, 2, 3, 4, 6}中，{8, 6}是峰， {5, 2}是谷。现在给定一个整数数组，将该数组按峰与谷的交替顺序排序。
\n\n示例:
\n\n输入: [5, 3, 1, 2, 3]\n输出: [5, 1, 3, 2, 3]\n\n\n
