Problem Description

Our lovely KK has a difficult mathematical problem:he has a  N(1≤N≤1018)  meters steel,he will cut it into steels as many as possible,and he doesn't want any two of them be the same length or any three of them can form a triangle.

 

Input

The first line of the input file contains an integer  T(1≤T≤10) , which indicates the number of test cases.

Each test case contains one line including a integer  N(1≤N≤1018) ,indicating the length of the steel.

 

Output

For each test case, output one line, an integer represent the maxiumum number of steels he can cut it into.

 

Sample Input

  
  

   
   1
6
  
  

 

Sample Output

  
  

   
   3


   
   

    
    

     
     Hint
    
    
1+2+3=6 but 1+2=3  They are all different and cannot make a triangle.

BestCoder Round #71 (div.2)

解体思路:在bc上提交时就WA了,在杭电上找到题目重新提交就过了,真不科学.

代码如下:

#include<stdio.h>
int main(){
	long long n,a,b,c,sum,ans;
	int t;
	scanf("%d",&t);
	while(t--){
		scanf("%lld",&n);
		a=1;b=2;sum=a+b;ans=1;
		if(n==1||n==2)printf("1\n");
		else{
		     while(sum<=n){
		     	ans++;
		        c=a+b;
		        sum+=c;
			a=b;
		        b=c;
		     }
			 printf("%lld\n",ans);	
		}
		
	}
	return 0;
}
