Problem Description
Fibonacci numbers are well-known as follow:
Now given an integer N, please find out whether N can be represented as the sum of several Fibonacci numbers in such a way that the sum does not include any two consecutive Fibonacci numbers.
Input
Multiple test cases, the first line is an integer T (T<=10000), indicating the number of test cases.
Each test case is a line with an integer N (1<=N<=109).
Output
One line per case. If the answer don’t exist, output “-1” (without quotes). Otherwise, your answer should be formatted as “N=f1+f2+…+fn”. N indicates the given number and f1, f2, … , fn indicating the Fibonacci numbers in ascending
order. If there are multiple ways, you can output any of them.
Example Input
4567100
Example Output
5=56=1+57=2+5100=3+8+89

题意:判断所给的数能不能由斐波那契数组成,如果能输出任意一种组成形式,不能输出-1
