Question

java求0—7所能组成的奇数个数

Answer 1

public class CountTest {

/**

* @param args

*/

public static void main(String[] args) {

// TODO Auto-generated method stub

int i = 7;

System.out.println("0—" + i + "所能组成的奇数个数：");

count(i);

}

public static int count(int num) {

if(num == 0)

return 0;

if(num == 1)

return 1;

int sum = 0;

int temp = 0;

if(num%2 == 0)

temp = num/2;

else

temp = num/2 + 1;

sum += temp;

System.out.println("1位数" + sum + "个,算法：偶数除以2；奇数除以2加1");

for(int i=0; i
