Problem Description

You will be given a string which only contains ‘1’; You can merge two adjacent ‘1’ to be ‘2’, or leave the ‘1’ there. Surly, you may get many different results. For example, given 1111 , you can get 1111, 121, 112,211,22. Now, your work is to find the total number of result you can get.

 

Input

The first line is a number n refers to the number of test cases. Then n lines follows, each line has a string made up of  ‘1’ . The maximum length of the sequence is 200.

 

Output

The output contain n lines, each line output the number of result you can get .

 

Sample Input

   
   
   
   

    
    
    
    3 1 11 11111
   
   
   
   

 

Sample Output

   
   
   
   

    
    
    
    1 2 8
   
   
   
   

 

 

和南阳OJ上的655题《光棍的yy》一样，代码题解相同，代码如下：

 

#include<stdio.h>
#include<string.h>
int a[205][102];//注意此处要比底下函数中的j的最大值开的大一点 

void count()
{
	int i,j,p,q;
	memset(a,0,sizeof(a));//数组清零 
	a[1][0]=1;a[2][0]=2;
	for(i=3;i<203;i++)//以下步骤模拟大数计算，初始化斐波那契数列 
	{
		p=q=0;
		for(j=0;j<=100;j++)
		{
			p=a[i-1][j]+a[i-2][j]+q;
			a[i][j]=p%10;
			q=p/10;
		}
	}
}

int main()
{
	count();
	int n,i,j,len;
	char s[205];
	scanf("%d",&n);
	while(n--)
	{
		getchar();
		scanf("%s",s);
		len=strlen(s);
		for(i=100;i>=0;i--)//找到数值的最后一位 
		    if(a[len][i]!=0)
		       break;
		for(j=i;j>=0;j--)// 注意上面的函数计算的值的数位是逆序的 
		   printf("%d",a[len][j]); 
		printf("\n");
	}
	return 0;
}
