07. Left and Right Sum

package main

import (
    "fmt"
    "math"
)

func main() {
    var n, number int
    fmt.Scanln(&n)

    var leftSum = 0
    var rightSum = 0

    for i := 0; i < n; i++ {
        fmt.Scanln(&number)
        leftSum += number
    }

    for i := 0; i < n; i++ {
        fmt.Scanln(&number)
        rightSum += number
    }

    if (leftSum == rightSum) {
        fmt.Printf("Yes, sum = %d\n", leftSum)
    } else {
        fmt.Printf("No, diff = %d\n", int(math.Abs(float64(leftSum - rightSum))))
    }
}

ИЛИ:

package main

import (
    "fmt"
    "math"
)

func main() {
    var n, number int
    fmt.Scanln(&n)

    var leftSum = 0
    var rightSum = 0

    for i := -n; i < n; i++ {
        fmt.Scanln(&number)
        if (i < 0) {
            leftSum += number
        } else {
            rightSum += number
        }
    }

    if (leftSum == rightSum) {
        fmt.Printf("Yes, sum = %d\n", leftSum)
    } else {
        fmt.Printf("No, diff = %d\n", int(math.Abs(float64(leftSum - rightSum))))
    }
}
