求出用1,2,5这三个数不同个数组合的和为1000的组合个数
public class getNumbers {
public static void sums1(int temp) {int num1 = temp / 1;
int num2 = temp / 2;
int num3 = temp / 5;
int numbers = 0;
String values;
for (int i = 0; i < num1; i++) {
for (int j = 0; j < num2; j++) {
for (int k = 0; k < num3; k++) {
if ((1 * i + 2 * j + 5 * k) == temp) {
numbers++;
values = i + "个1," + j + "个2," + k + "个5";
System.out.println("the " + numbers + " groups numbers is:" + values);
}
}
}
}
System.out.println("the numbers of group is ===>" + numbers);
}
public static void main(String[] args) {
int s = 1000;
sums1(s);
}
}
