解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String [] args) {

Scanner scan=new Scanner(System.in);

int i = 1;

long sum = 1,x, add = 1, n, k, T;

n=scan.nextLong();

k=scan.nextLong();

T=scan.nextLong();

while (i<T){

  x = add + ((i - 1)*n + 1 + i*n)*n / 2;

  i++;

  x = x%k;

  sum += x;

  add = x;

}

System.out.print(sum);

}

}
