P1634題解

import java.util.Scanner;public class Main {public static void main(String[] args) {long sum = 1L;Scanner scan = new Scanner(System.in);int a = scan.nextInt(), b = scan.nextInt();scan.close();if (a > 0) {if (b > 0) {for (int i = 0; i < b; i++) {sum += sum*a;}}}System.out.println(sum);}}

P1888題解

import java.util.Scanner;public class Main {public static void main(String[] args) {int maxNumber, minNumber, a;Scanner scan = new Scanner(System.in);int x = scan.nextInt(), y = scan.nextInt(), z = scan.nextInt();if (x >= y && x >= z) {maxNumber = x;if (y >= z)minNumber = z;elseminNumber = y;} else if (y >= x && y >= z) {maxNumber = y;if (x >= z)minNumber = z;elseminNumber = x;} else {maxNumber = z;if (x >= y)minNumber = y;elseminNumber = x;}int number1 = maxNumber;int number2 = minNumber;while(number2!=0){int r = number1 % number2;number1 = number2;number2 = r;}//在while過程中，a與b的值會發生改變，所以需要將a，b的值賦給oa,ob//oa與ob的最大公約數是aa = number1;minNumber /= a;maxNumber /= a;System.out.println(minNumber + "/" + maxNumber);scan.close();}}
