The code below counts the sum of numbers from a range. Altogether, you need to find three sums: the sum of numbers divisible by three, the sum of numbers divisible by five, and the sum of all other numbers. The range is defined by two numbers that you get from standard input. The first number is the beginning of the range, and the second number is the end of it, both numbers included.
The code below contains a goto statement, and you need to rewrite it without using goto.
package main
import "fmt"
func main() {
var numberRange, end, sum3, sum5, other int
fmt.Scan(&numberRange, &end)
StartOfLoop:
switch {
case numberRange%3 == 0:
goto amount3
case numberRange%5 == 0:
goto amount5
default:
goto otherAmount
}
amount3:
sum3 += numberRange
goto EndOfLoop
amount5:
sum5 += numberRange
goto EndOfLoop
otherAmount:
other += numberRange
EndOfLoop:
numberRange++
if numberRange <= end {
goto StartOfLoop
}
fmt.Println(sum3)
fmt.Println(sum5)
fmt.Println(other)
}
In case of difficulties, just see the hint.
Tip:
package main
import "fmt"
func main() {
var numberRange, end, sum3, sum5, other int
fmt.Scan(&numberRange, &?)
for ? <= end {
switch {
case numberRange%3 == 0:
sum3 += ?
case ? == 0:
? += numberRange
default:
other += ?
}
numberRange++
}
fmt.Println(sum3)
fmt.Println(?)
fmt.Println(other)
}
