蓝桥杯历届试题-数字游戏-题解(Java代码)

解题思路:

注意事项:

参考代码:

package Test;

import java.util.Scanner;

public class Lq1443 {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

long n = sc.nextLong();

long k = sc.nextLong();

long T = sc.nextLong();

long sum = 1l;//和

long x = 1l;//记录每次的数字

long y = (n+n*n)/2;

//an=a1+(n-1)d d=1;

for(int i=1;i<T;i++){

x=(x+y)%k;

y=y+n*n;

sum=sum+x;

}

System.out.println(sum);

}

}
