How to find the sum of cells in go?
问题
实现SumCells(cells)函数。
输入：一个任意的Cell变量集合cells。
返回：一个单独的Cell变量，对应于对cells中每个单元格中的元素求和。
type Cell [2]float64
func SumCells(cells ...Cell) Cell {
sum := Cell{}
for _, row := range cells { // 遍历行
for cellIndex, cell := range row {
sum[cellIndex] += cell
}
}
return sum
}
有人可以解释一下如何编写这个函数吗？
英文:
Implement the function SumCells(cells).
Input: an arbitrary collection cells of Cell variables.
Return: a single Cell variable corresponding to summing corresponding elements in every cell in cells.
type Cell [2]float64
func SumCells(cells ...Cell) Cell {
sum := 0.0
var c Cell
c = append(c, cells)
for rowIndex, row := range cells { // loop through rows
for cellIndex := range row {
sum += [rowIndex][cellIndex]
}
}
return c
}
Could someone explain how to write this function?

Cell是一个一维数组或简单数组，在SumCells函数中，Cell或[]Cell需要一个Cells数组[]Cell{{1,3}, {3, 4}}，所以你可以简单地这样做Go Playground
func SumCells(cells []Cell) float64 {
var sum float64
for _, cell := range cells {
sum += cell[0] + cell[1]
}
return sum
}
英文:
Cell is a single dimensional array or simple array and in SumCells ...Cell or []Cell want's an array of Cells []Cell{{1,3}, {3, 4}} so you can simply do this Go Playground
func SumCells(cells []Cell) float64 {
var sum float64
for _, cell := range cells {
sum += cell[0] + cell[1]
}
return sum
}

以下是翻译好的内容：
func SumCells(cells ...Cell) (sum Cell) {
for _, c := range cells {
sum[0] += c[0]
sum[1] += c[1]
}
return sum
}
type Cell [2]float64
或者，如果你想要未来能适应Cell中元素数量的变化：
func SumCells(cells ...Cell) (sum Cell) {
for _, c := range cells {
for i, v := range c {
sum[i] += v
}
}
return sum
}
type Cell [2]float64
英文:
Something like this should do you:
func SumCells(cells ...Cell) (sum Cell) {
for _, c := range cells {
sum[0] += c[0]
sum[1] += c[1]
}
return sum
}
type Cell [2]float64
Or, if you wanted to future-proof yourself in case the number of elements in a Cell changes:
func SumCells(cells ...Cell) (sum Cell) {
for _, c := range cells {
for i, v := range c {
sum[i] += v
}
}
return sum
}
type Cell [2]float64

// Cell是一个二维点
type Cell [2]float64
// SumCells将一组cell相加
func SumCells(cells ...Cell) Cell {
var sum Cell
for _, cell := range cells {
sum = sum.Add(cell)
}
return sum
}
// Cell.Add将两个cell相加
// 这是Cell类型的方法
func (c Cell) Add(other Cell) Cell {
return Cell{
c[0] + other[0],
c[1] + other[1],
}
}
英文:
// Cell is a 2D point
type Cell [2]float64
// SumCells adds a bunch of cells together
func SumCells(cells ...Cell) Cell {
var sum Cell
for _, cell := range cells {
sum = sum.Add(cell)
}
return sum
}
// Cell.Add adds two cells together
// This is a method on the Cell type
func (c Cell) Add(other Cell) Cell {
return Cell{
c[0] + other[0],
c[1] + other[1],
}
}
