Problem Description

A Fibonacci sequence is calculated by adding the previous two members the sequence, with the first two members being both 1.
F(1) = 1, F(2) = 1, F(3) = 1,F(4) = 1, F(n>4) = F(n - 1) + F(n-2) + F(n-3) + F(n-4)
Your task is to take a number as input, and print that Fibonacci number.

Input

Each line will contain an integers. Process to end of file.

Output

For each case, output the result in a line.

Sample Input

100

Sample Output

4203968145672990846840663646

题解：大数相加超内存，所以想着每个里面存8位；输出的时候不足8位补0；

代码：

 #include<stdio.h>
 #include<string.h>
 const int MAXN=;
 const int MAXM=;
 char temp[MAXN];
 int dp[MAXN][];
 int main(){
     dp[][]=;
     dp[][]=;
     dp[][]=;
     dp[][]=;
     dp[][]=;
     for(int i=;i<=;i++){
         for(int j=;j<=;j++)dp[i][j]=dp[i-][j]+dp[i-][j]+dp[i-][j]+dp[i-][j];
         for(int j=;j<=;j++)
             if(dp[i][j]>MAXM)dp[i][j+]+=dp[i][j]/MAXM,dp[i][j]%=MAXM;
     }
     int n;
     while(~scanf("%d",&n)){
         int j=;
         while(!dp[n][j])j--;
         printf("%d",dp[n][j]);
         while(--j>=)printf("%08d",dp[n][j]);//不足8位补零
         puts("");
     }
     return ;
 }
