	双指针:
	```scala
	object Solution {
	def sortedSquares(nums: Array[Int]): Array[Int] = {
	val res: Array[Int] = new Array[Int](nums.length)
	var top = nums.length - 1
	var i = 0
	var j = nums.length - 1
	while (i <= j) {
	if (nums(i) * nums(i) <= nums(j) * nums(j)) {
	// 当左侧平方小于等于右侧,res数组顶部放右侧的平方,并且top下移,j左移
	res(top) = nums(j) * nums(j)
	top -= 1
	j -= 1
	} else {
	// 当左侧平方大于右侧,res数组顶部放左侧的平方,并且top下移,i右移
