请问一下该golang语句中逗号的使用方法
for i := 0; i < len(levelOrder) / 2; i++ {
levelOrder[i], levelOrder[len(levelOrder) - 1 - i] = levelOrder[len(levelOrder) - 1 - i], levelOrder[i]
}
for i := 0; i < len(levelOrder) / 2; i++ {
levelOrder[i], levelOrder[len(levelOrder) - 1 - i] = levelOrder[len(levelOrder) - 1 - i], levelOrder[i]
}
