我有两个函数递归和迭代来计算货币变化;在迭代版本中我需要检查钱是否是变化的倍数（货币模数变化为零）：有没有办法在不检查模数的情况下进行迭代？
public static int MoneyChangeRecur(int money, int[] changes)
{
int minChange = 0;
if (money == 0) return 0;
int min = int.MaxValue;
for (int i = 0; i < changes.Length; i++)
{
if (money >= changes[i])
{
minChange = MoneyChangeRecur(money - changes[i], changes);
if (minChange + 1 <= min)
{
min = minChange + 1;
}
}
}
return min;
}
static int IterativeMoneychange(int money)
{
int[] ar = new int[money + 1];
int[] change = { 6, 5, 1 };
int min = 9999;
int index = 0;
for (int i = 0; i < money+1; i++)
{
min = 99999;
index = 0;
bool modSet = false;
for (int j= 0; j <change.Length; j++)
{
if (i >= change[j])
{
int mod=(i % change[j]);
if(mod==0&&change[j]!=1)
{
if (!modSet) min = 99999;
if ((i-change[j] )< min)
{
min = (i - change[j]);
modSet = true;
}
}
else
{
if ((i - change[j]) < min)
{
min = (i - change[j]);
modSet = false;
}
}
}
}
if (min != 99999)// min = 0;
ar[i] = ar[min] +1;
}
return ar[money];
}enter code here
