AtCoder Beginner Contest 180のメモ

前置き

Atcoderをやってみたので、自分用のメモです。
あとから加筆・修正する予定です。

問題

A

Q_A.go
package main

import (
    "fmt"
)

func main() {
    var n, a, b int
    fmt.Scanf("%d %d %d", &n,&a,&b)

    fmt.Printf("%d\n", n-a+b)
}

B

Q_B.go
package main

import (
    "fmt"
    "math"
)

func main() {
    var n int
    fmt.Scanf("%d", &n)

    var t int
    manhattan :=0
    euqulid :=0
    chebishev :=0

    for i := 0; i < n; i++ {
        fmt.Scanf("%d", &t)

        if t > 0 {
            manhattan += t
        }else{
            manhattan -= t
        }

        euqulid += t*t

        if t > 0 {
            if t > chebishev{
                chebishev = t
            }
        }else{
            if -t > chebishev{
                chebishev = -t              
            }  
        }
    }

    fmt.Printf("%d\n", manhattan)

    fmt.Printf("%.10f\n", math.Sqrt(float64(euqulid)))

    fmt.Printf("%d\n", chebishev)

}

C

Q_C.go
package main

import (
    "fmt"
)

func main() {
    var n int
    fmt.Scanf("%d", &n)

    max := make([]int, 1)

    for i:=1; i*i<n+1; i++{
        if n % i == 0{
            if n/i != i{
                max = append(max, n/i)
            }
            fmt.Printf("%d\n", i)
        }
    }


    for i:=len(max)-1; i>0; i--{
        if max[i] != 0{
            fmt.Printf("%d\n", max[i])
        }
    }
}

D

Q_D.go
package main

import (
    "fmt"
)

func main() {
    var x, y, a, b uint64
    fmt.Scanf("%d %d %d %d", &x, &y, &a, &b)

    var cnt uint64 = 0

    for x < y/a & b/(a-1) {
        cnt++
        x *= a
    }

    cnt += (y-1-x)/b

    fmt.Printf("%d\n", cnt)
}
