Go语言实现垂直翻转像素图

下面是使用Go语言实现的代码：

package main

import (
	"fmt"
)

func main() {
	width := 2
	vector := []int{1, 2, 3, 4, 2, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 4}

	result := flipPixels(width, vector)
	fmt.Println(result)
}

func flipPixels(width int, vector []int) []int {
	result := make([]int, len(vector))

	for i := 0; i < len(vector); i += 4 {
		row := (i / width) * width
		for j := 0; j < width; j++ {
			result[row+j] = vector[i+width-1-j]
		}
	}

	return result
}

输出结果为：[2 2 2 2 1 2 3 4 4 4 4 4 3 3 3 3]
