package main
import "fmt"
func main() {
min := int8(127)
max := int16(1000)
fmt.Println(max + int16(min))
// EXPLANATION
//
// `int8(max)` destroys the information of max
// It reduces it to 127
// Which is the maximum value of int8
//
// Correct conversion is int16(min)
// Because, int16 > int8
// When you do so, min doesn't lose information
//
// You will learn more about this in
// the "Go Type System" section.
