和为n的连续正数序列

public static void main(String[] args)
{
int n = 15890;
int small = 1;
int big =2;
int mid = (1+n)/2;
int sum = small+big;
while(small<mid)
{
if(sum == n)
{
for (int i = small; i <=big; i++)
{
System.out.print(i+" ");
}
System.out.println();
}
while(sum>n)
{
sum-=small;
small++;
if(sum == n)
{

{
System.out.print(i+" ");
}
System.out.println();
