04. Sum of Two Numbers

package main

import "fmt"

func main() {
   var startNum, endNum, magicNum, counter int
    fmt.Scanln(&startNum)
    fmt.Scanln(&endNum)
    fmt.Scanln(&magicNum)

    var isMagic = false

    for i := startNum; i <= endNum; i++ {
        for j := startNum; j <= endNum; j++ {
            counter++
            if i + j == magicNum {
                fmt.Printf("Combination N:%d (%d + %d = %d)\n", counter, i, j, magicNum)
                isMagic = true
                break
            }
        }
        if isMagic == true {
            break
        }
    }

    if isMagic == false {
        fmt.Printf("%d combinations - neither equals %d\n", counter, magicNum)
    }
}

ИЛИ:

package main

import "fmt"

func main() {
   var startNum, endNum, magicNum, counter int
    fmt.Scanln(&startNum)
    fmt.Scanln(&endNum)
    fmt.Scanln(&magicNum)

    for i := startNum; i <= endNum; i++ {
        for j := startNum; j <= endNum; j++ {
            counter++
            if i + j == magicNum {
                fmt.Printf("Combination N:%d (%d + %d = %d)\n", counter, i, j, magicNum)
                return
            }
        }
    }

    fmt.Printf("%d combinations - neither equals %d\n", counter, magicNum)
}
