We all know the definition of Fibonacci series: fib[i]=fib[i-1]+fib[i-2],fib[1]=1,fib[2]=1.And we define another series P associated with the Fibonacci series: P[i]=fib[4*i-1].Now we will give several queries about P:give two integers L,R, and calculate ∑P[i](L <= i <= R).
输入解释
There is only one test case. The first line contains single integer Q – the number of queries. (Q<=10^4) Each line next will contain two integer L, R. (1<=L<=R<=10^12)
输出解释
For each query output one line. Due to the final answer would be so large, please output the answer mod 1000000007.
