int i=5,a;
for(int j=i; j>=1; j--) {
for(a=1; a<=i; a++)
System.out.print(a +" + ");
int n = 0;
for(a = 1; a<=i; a++) {
n = n + a;
}
System.out.print(" = "+ n);
System.out.println();
i--;
}
}
}
推荐答案
通过获取用户的输入,您可以对任何n个输入
You can do it for any n, by getting input from the user
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
for (int i = 1; i <= n; i++) {
int add = 0;
for (int j = 1; j <= i; j++) {
System.out.print(j);
if (j == i)
System.out.print("=");
else
System.out.print("+");
add += j;
}
System.out.println(add);
}
