find the midpoint between two points in go

To find the midpoint between two points (x1, y1) and (x2, y2), we can use the following formula:

midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)

In Go, we can create a function that takes in two points as arguments and returns the midpoint as a new point.

main.go
package main

import "fmt"

type point struct {
  x float64
  y float64
}

func midpoint(p1, p2 point) point {
  return point{(p1.x + p2.x) / 2, (p1.y + p2.y) / 2}
}

func main() {
  p1 := point{1.0, 2.0}
  p2 := point{3.0, 4.0}
  fmt.Println(midpoint(p1, p2)) // Output: {2 3}
}

In the above code, we define a point struct that represents a point in 2D space with an x and y coordinate. The midpoint function takes in two points p1 and p2, and returns the midpoint as a new point by applying the formula mentioned above. Finally, in the main function, we create two points p1 and p2 and find their midpoint by calling the midpoint function.
