不同的面值Value[ ]有硬币个数Num[ ]限制，凑齐Goal面值,需要的最小和最大个数。

static int  Min = 1<<10;
static  int Max = 0;
static int* set;
static int* Count;


void LeastCoin_N(int* Value, int* Num, int Len, int Goal, int cur) 
{   
	if(Goal == 0) 
	{
		if(cur > Max)
		{
			for(int i = 0; i < Len; i++)
			{		
				for(int j = 0; j < cur; j++)
				{
					if(Value[i] == set[j])
					{
						Count[i]++;
						if(Count[i] > Num[i])
						{
							goto  initial;
						}
					}

				}
			}

			for(int i = 0; i < cur; i++)
			{
			     printf("%d ", set[i]);  
			}
			Max = cur;
		}
		if(Min > cur)
		{			
			for(int i = 0; i < Len; i++)
			{		
				for(int j = 0; j < cur; j++)
				{

initial:	
		memset(Count, 0 , sizeof(int)*Len);
